Inbreeding

From WikiMD.com Medical Encyclopedia

Reproduction from the mating of individuals closely related genetically


Inbreeding[edit | edit source]

Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the practice in animal breeding and plant breeding.

Genetic Implications[edit | edit source]

Inbreeding results in an increase in homozygosity, which can increase the chances of offspring being affected by recessive or deleterious traits. This is because closely related individuals are more likely to carry the same alleles, including those that are deleterious.

Inbreeding Depression[edit | edit source]

Inbreeding depression is a reduction in biological fitness in a given population as a result of inbreeding. Biological fitness refers to an organism's ability to survive and reproduce. Inbreeding depression is often the result of a population bottleneck.

Inbreeding in Humans[edit | edit source]

In humans, inbreeding is often associated with consanguinity, which refers to the genetic relatedness between individuals. Consanguineous marriages are more common in certain cultures and can lead to an increased risk of genetic disorders.

Inbreeding in Animals[edit | edit source]

In animal breeding, inbreeding is used to preserve desirable traits within a population. However, it can also lead to inbreeding depression, which can reduce the overall health and viability of the population.

Selective Breeding[edit | edit source]

Selective breeding is a process used by humans to develop new organisms with desirable characteristics. Inbreeding is sometimes used in selective breeding to ensure that these traits are passed on to future generations.

Inbreeding in Plants[edit | edit source]

In plants, inbreeding can occur naturally or be induced by humans. It is often used in plant breeding to create pure lines for research or agricultural purposes.
