A gene that is fully expressed in a heterozygote. A dominant gene may partially or entirely suppress the expression of another allelic gene (recessive gene).
A gene that is expressed even when its allele on its paired chromosome is different.
a gene that always produces its effect when it is present
A gene capable of expressing its trait even when carried by only one member of a chromosome pair.
One of a pair of genes that predominates over the other and determines that the trait it fosters will prevail in the phenotype.
gene determining phenotype, allelic pair is therefore resessive.(More? DNA Notes)
Since genes come in pairs, a dominant gene is always expressed (message is read) regardless of the message on the other gene.
gene that produces the same phenotype in the organism whether or not its allele identical; "the dominant gene for brown eyes"
an expressed characteristic trait within an organism, where as a recessive trait is not
A gene which, when present on a chromosome, passes on a certain physical characteristic, even when the gene is present in only one copy. A dominant disorder can be inherited from only one parent.
gene that requires only one of two copies (inherited from either parent) to cause a trait to express (see also recessive gene).
a gene which passes on a certain physical characteristic, dominating over a recessive gene present on another chromosome.
A gene that is fully expressed in the phenotype of the heterozygote. www.pestmanagement.co.uk/library/gloss_d2.html-- A member of a gene pair which, if present, determines that the individual will show the trait controlled by the gene, regardless of whether the other member of the pair is the same or different (that is, recessive). See also recessive gene. lms.thomsonelearning.com/hbcp/glossary/glossary.taf
Principle first observed by Mendel that one gene may prevent the expression of al allele or so-called recessive gene when they are present together at the same points on each of a pair of chromosomes.
A gene that always shows itself in the phenotype of a hamster. In genetics, these genes are denoted with a Capital letter.
A gene that produces the same phenotype, whether or not the other gene in the pair is identical. It will "cover up" the other gene. For example, a black dog only needs to be carrying one gene for black. Even if the other gene is red (brown), the black will override it. See also recessive gene.
A gene that is "expressed." One that "wins" over a recessive gene in determining how the offspring will develop.
A gene, whose presence as a single copy, controls the expression of a trait.
referring to a genetic trait present in one parent that is expressed in the offspring, regardless of whether the trait is present in the other parent.
A gene that almost always results in a specific physical characteristic, for example, a disease, even though the patient's genome possesses only one copy. With a dominant gene, the chance of passing on the gene (and therefore the disease) to children is 50-50 in each pregnancy. [Talking Glossary
