Mating or crossing of individuals more closely related that average pairs in the population.
The mating of individuals that are closely related genetically.
The raising of progeny by mating of two or more closely related gametes or zygotes.
This occurs when a female is mated with a male to which she is related. The more closely related the two are, the more intense the degree of inbreeding.
Production of offspring by (blood) related parents. Its most extreme form is self-fertilization in hermaphrodites (most invertebrates and plants).
In plants, a breeding system where sexual reproduction involves the interbreeding of closely related plants, such as by self-pollination.
The level of compatibility between homokaryons derived from one dikaryotic or diploid parental genotype following meiosis.
Breeding closely related horses to obtain a desired trait. Examples of inbreeding include: parent to progeny, full or half-siblings to one another, breeding first cousins, uncles to nieces and/or aunts to nephews, and grandparents to grandchildren.
Matings between close relatives.
The mating of animals more closely related than the average of the population.
Preferential mating between relatives, extreme inbreeding: mating between sibs, half-sibs, parent-offspring, see Outbreeding
the act of mating closely related individuals
Mating between closely related individuals in a population, eventually resulting in a decrease in the total amount of genetic variation present.
Breeding together two animals who are closely related to one another. Compare to Linebreeding and Outcrossing. For more information: Inbreeding vs. Linebreeding.
Deliberate mating of closely related individuals to preserve desirable characteristics as in father-daughter, mother-son, sister-brother.
breeding through a succession of parents that are closely related potentially resulting in reduced fitness.
The process of repeatedly mating sequential generations of sibling animals, usually mice. Within an inbred strain, same-sex animals are genetically identical and have two identical copies of each allele at corresponding loci of the paired chromosomes.
The breeding results of broken/inadequate pasture fencing.
mating among individuals that are very closely related
the crossing of two closely related beings.
a breeding technique which pairs closely related animals, such as father-daughter, brother-sister, or cousins. Inbreeding favors genes of excellence as well as deleterious genes.
mating among close relatives. This often leads to severe abnormalities in offspring as a result of little genetic variability between mating pairs.
The process of a continual sequence of crossing between the offspring of a small, often isolated group of organism. Inbreeding generally results in an increase in the genetic similarity between individuals in the group since no new genes are produced. Volume 3, Number 4 Hibiscus International August-October 2003
( Genet.). Crossing between a succession of parents derived from a single origin, or from the selfing of a single parent. ( BCFT). Anton. Outbreeding.
Production of offspring from parents more closely related than the average of a population. Inbreeding increases the proportion of homozygous gene pairs and decreases the proportion of heterozygous gene pairs. Also, inbreeding increases prepotency and facilitates expression of undesirable recessive genes.
The mating of relatives.
In Breeding- What, Why, and How Inbreeding (Genetics of the Dog)
the crossing of closely related plants or animals
Mating between close relatives.
The mating of related individuals.
Mating between closely related individuals. This can lead to a loss of vability in the population due to accumulation of undesirable alleles passed on from a common ancestor.
A breeding program involving the mating of closely related rabbit stock, such as brother and sister.
A mating system in which mates are more closely related genetically than the average of the population in which they belong.
The breeding of two animals closely related in blood.
The mating of brother/sister, sire/daughter, son/dam, to fix or accentuate a particular trait or character.
The mating of closely related dogs of the same breed.
When closely related animals have offspring together.
Breeding together closely related fowls. For example a brother and sister.
The breeding of related individuals.
The mating of two closely related cats of the same breed.
Mating of closely related parents, i.e. brother to sister, mother to son, etc.
Mating of closely related individuals or of individuals having similar gene type (genotype).
Mating closely related animals.
The mating if two closely-related cats; such as, a mother and son or brother and sister. There are no rules in CFA against the registration of kittens produced from such a breeding.
mating of genetically similar individuals, usually relatives. Homozygosity increases with eachsuccessive generation. Tends to decrease variability in the population. Compare with outbreeding.
Matings between related individuals.
Inbreeding is breeding between close relatives, whether plant or animal. If practiced repeatedly, it often leads to a reduction in genetic diversity, and the increased expression of negative recessive traits, resulting in inbreeding depression. This may result in inbred individuals exhibiting reduced health and fitness and lower levels of fertility.
Where the same horse's name appears within the tabulated pedigree (q.v.) of the subject animal twice or more. It may occur more than once in the sire's half of the pedigree, or in the dam's half, or several times in both halves. There is a greater chance of this horse having passed various influences through his/her genes to the subject animal than other horses in the pedigree whose names appear only once. Abbreviation for Listed (see Listed race)
The result of inadequate fencing
