UC Berkeley. In a small population, matings between relatives are common. For example, a population of 40 adders Vipera berusshown at right experienced inbreeding depression when farming activities in Sweden isolated them from other adder populations. Higher proportions of stillborn and deformed offspring were born in the isolated population than in the larger populations.
Inbreeding depression is the reduced biological fitness that has the potential to result from inbreeding the breeding of related individuals. Biological fitness refers to an organism's ability to survive and perpetuate its genetic material. Inbreeding depression is often the result of a population bottleneck. In general, the higher the genetic variation or gene pool within a breeding population, the less likely it is to suffer from inbreeding depression, though inbreeding and outbreeding depression can simultaneously occur. Inbreeding depression seems to be present in most groups of organisms, but varies across mating systems.

Additional Information. Last updated on May 25, Get Started. English Hindi. This question was previously asked in. Attempt Online. Cross breeding Out breeding Out crossing Interspecific hybridization. Start Now. Concept: Inbreeding refers to the mating between closely related individuals within the same breed for 4 - 6 generations. Close inbreeding usually results in the reduction of fertility and productivity.
For example, a mule was obtained by crossing a male donkey and a female horse. The disease caused by breathing polluted air is:. Speed of sound is highest in which medium?

More Biology Questions Q1. Another mechanism responsible for inbreeding depression is the fitness advantage of heterozygosity, which is known as overdominance. More Zoology Questions Q1. In the case of the Swedish adders, that meant stillborn offspring and deformities. Biogeography Evolution Evolutionary game theory Fitness landscape Genetic genealogy Landscape genetics and genomics Microevolution Population genomics Phylogeography Quantitative genetics. The energy-rich compound formed during respiration is. Some recessive genes result in detrimental phenotypes by causing the organism to be less fit to its natural environment. More General Science Questions Q1. Cross breeding Out breeding Out crossing Interspecific hybridization. Suggested Exams. By having several copies of a chromosome, as opposed to two, homozygosity is less likely to occur in inbred offspring. Get Started. In other projects. The progeny may or may not be of economic value.
Inbreeding depression is the reduced biological fitness that has the potential to result from inbreeding the breeding of related individuals.
Evolutionary Psychology. When the relatives mate, the offspring may inherit two copies of the same recessive deleterious allele and suffer the consequences of expressing the deleterious allele, as shown in the example below. Inbreeding may have both detrimental and beneficial effects. Download as PDF Printable version. White light is composed of how many colours? Introduction to conservation genetics. By having several copies of a chromosome, as opposed to two, homozygosity is less likely to occur in inbred offspring. An example of inbreeding depression is shown to the right. Annals of Human Biology. Evol Lett. Get Started. The offspring is known as an out-cross. For example, the outcrossing nematode roundworm Caenorhabditis remanei has been demonstrated to suffer severely from inbreeding depression, unlike its hermaphroditic relative C.
