A person who possesses at least one gene that may contribute to disease in offspring.
Carrier is an analog or digital signal of constant and known characteristics, over which modifications are inserted. These modifications represent the information to be transmited.
A person, generally in apparently good health, who has been infected with a pathogen and is capable of infecting and causing disease in others. Individuals persistently infected with hepatitis C are considered carriers.
An individual with one normal and one abnormal copy of a pair of genes which cause a genetic disorder. A carrier of a gene for a recessive disorder will usually remain unaffected throughout his or her life but may pass the faulty gene on to offspring. search for Carrier
A healthy individual who has both a normal and an abnormal copy of a pair of genes for a genetic disorder or characteristic. A carrier of a gene for a recessive disorder will usually remain unaffected throughout life.
Someone who's capable of transmitting a disease (especially an infectious or genetic disorder) to another person but who usually has no symptoms of the disease.
A person who does not suffer from a recessive genetic debilitation, but who carries genes for it that can be passed along to offspring.
an animal that harbours a disease-causing organism in its body, and which appears healthy and does not exhibit outwards signs of disease, thus acting as a carrier or distributor of the disease.
A person or animal that harbors a specific infectious agent in the absence of discernible clinical disease and serves as a potential source of infection.
A person who has one copy of a particular gene mutation, and one copy that is healthy. In autosomal recessive disorders carriers show no symptoms of the disorder, in most cases, because a person must have two copies of the gene mutation for the disorder to be expressed. In X-linked recessive disorders, females are carriers, because they have an healthy allele on their second X chromosome to "protect" them from symptoms of the disease.
A person in apparent good health who harbors a pathogenic microorganism.
A person who has one recessive gene for a recessive genetic disease. Because the person has only one recessive gene, s/he does not have the disease, but can pass the disease gene on to her/his children.
One who can transmit a disease to others.
An individual who carries an infectious agent without manifesting symptoms, yet who can transmit the agent to another individual
Is a person who is infected with an agent that causes a disease who shows no sign of illness. Asymptomatic carriers shed the causative agent, such as a virus or bacteria, and so can pass the disease on to others. The most famous asymptomatic carrier was Mary Mallon, or Typhoid Mary.
Person or animal having a specific infectious agent with no clinical signs of disease but capable of transmitting the agent.
An individual heterozygous for a single recessive gene. Has one normal copy and one mutant allele (copy of the gene).
An individual who possesses a mutant allele but does not express it in the phenotype, either because of a dominant allelic partner or because the mutation is nonpenetrant.
A person who may pass on a condition or hereditary characteristic without suffering from or showing symptoms of it.
An individual who carries a allele of a gene associated with a disease. In many cases, the carrier may not actually have the disease associated with the version of they gene they carry, even though they may pass it on to their offspring.
Any animal or person who harbors disease-causing bacteria in the body without having noticeable symptoms. A carrier can transmit the bacteria to other persons through direct contact or through food.
A person who carries an infectious agent but shows no symptoms of infection.
A person who harbors an infectious disease (such as hepatitis) without any clinical signs of it and is a potential source of infection.
An individual that has a gene or genes for a particular trait, but does not exhibit that trait.
An individual who has one copy (allele) of a disease-causing gene. Carriers do not usually express the condition caused by the recessive allele, but can pass it on to their offspring. Examples: A carrier for cystic fibrosis or sickle cell anemia.
An individual who has a disease-causing gene mutation on one chromosome of a pair, and a normal version of the gene on the other. Usually refers to unaffected carriers of recessive conditions. An individual who has a balanced chromosome translocation.
A person who has one out of two genes for an inheritable condition, without being affected by the condition.
Individuals with one abnormal gene in their gene pair. These individuals do not show evidence of the disorder.
a person or animal that harbors a specific infectious agent and serves as a potential source of infection, yet does not manifest any clinical signs of disease
A person who has an infection and can transmit the infection to another without knowledge of symptoms or infection.

A person who has both a healthy gene and an abnormal copy of a pair of genes for a genetic disorder or characteristic. The carrier does not themselves have the trait.
An individual who has a gene mutation for a recessive disease on one allele while the other allele is normally functioning. This individual most often does not develop symptoms of the disease, but is at risk of having a child with the disease if their partner is also a carrier.
A person that has a specific infectious agent and is a potential source of infection. Hepatitis B carriers may never become sick but are able to infect others with the virus.
An individual who carries a single altered gene for a condition where two altered genes are required for an individual to be affected. The carrier can pass on the altered gene to their offspring, who may be affected if they also inherit another altered gene from their other parent. A carrier is a heterozygote for the gene carried.
person with an inapparent infection who sheds pathogens and can therefore transmit disease
person who carries one copy of a disease causing gene, but does not have the actual disease. This person has the potential to pass the disease onto his/her children if the spouse is a carrier as well.
animal that acts as a host for a disease and spreads it to others.

A healthy person who is a heterozygote for a recessive trait. Also refers to a person with a balanced chromosomal translocation.
Usually refers to an individual who is heterozygous for a recessive, disease-causing allele. A carrier of such an allele usually shows no symptoms of the disease but can pass the mutant allele on to his or her children. If both parents are carriers, there is a one in four chance that their child will be homozygous for the mutant allele and will be affected by the disease.
CDC defines the term disease carrier as implying "prolonged or indefinite survival, viral excretion, and ability to transmit infection." [Definition given in the Centers for Disease Control MMWR October 25, 2002, 51(42):963 in context of clarifying that bats and other mammals are not carriers of the rabies virus.] Merriam Webster defines a disease carrier as "a bearer and transmitter of a causative agent of an infectious disease; especially one who carries the causative agent of a disease systemically but is immune to it, [or] an individual (as one heterozygous for a recessive) having a specified gene that is not expressed or only weakly expressed in a phenotype.
An individual who possesses a mutant allele but does not express it in the phenotype, because of a dominant allelic partner; thus, an individual of genotype A a is a carrier of if there is complete dominance of over .
A person or animal without apparent disease who harbors a specific infectious agent and is capable of transmitting the agent to others. The carrier state may occur in an individual with an infection that is inapparent throughout its course (known as asymptomatic carrier), or during the incubation period, convalescence, and postconvalescence of an individual with a clinically recognizable disease. The carrier state may be of short or long duration (transient carrier or chronic carrier).
(1) A person of either gender who has inherited a disease-causing autosomal allele from one parent and a normal allele from the other parent. Inheritants of disease-causing alleles from both parents results in an autosomal recessive disease. (2) A female who possesses an allele on one of her X chromosomes (X-linked) which results in disease in males. In most cases, carriers suffer no ill effects from possession of the allele. "Heterozygote" for autosomal recessive or X-linked disorders is a synonym for "carrier." (3) A person who has inherited a single allele which results in an autosomal dominant disease.
A condition where an individual carries a particular non-working recessive gene but also has a working copy as well. This working gene usually prevents the manifestation of symptoms of the disease that the non-working gene causes. Individuals who are carriers can pass either the working or non-working gene (also referred to as a " trait") to their offspring with equal chance.

Historically, an individual who has one copy of a recessive, disease-causing gene mutation at a particular locus on one chromosome of a pair, and a normal allele at that locus on the other chromosome; may also refer to an individual with a balanced chromosome rearrangement. Current usage also applies this term to individuals who carry a single mutation in a gene such as BRCA1 and BRCA2, which behaves in an autosomal dominant manner within a family.
An individual who does not display the symptoms of a disease, but carries the gene (or genes) for it. A carrier can transmit the disease by passing the abnormal gene (or genes) to offspring. Synonym of heterozygote.
(KARE-ee-er) An individual who does not display the symptoms of a disease, but harbors the pathogen that causes it, or has the gene(s) for it, and can transmit the disease to others either through interacting with other individuals, or by passing the disease-causing gene(s) to offspring

an individual who carries a pathogen or a gene that causes a disease, but does not display symptoms of that diseases. This person may pass on the pathogen or gene thereby infecting another individual.
A person who has a recessive mutated gene and its normal allele. Carriers do not usually develop the disease but can pass the mutated gene to their children. In some cases, a person who is a carrier can develop the disease when his/her normal allele is lost or mutated.
an individual who has inherited an allele, which plays a role in disease, but who also has a normal allele which is a dominant allele. In most cases, carriers suffer no ill-effects from the disease-related allele, however they may pass the allele on to their children.
