Outbreeding can increase the genetic diversity and introduce elite alleles into the breeding population. Another outbreeding-derived genetic effect is hybrid vigor or heterosis which is utilized extensively in animal and plant production.

What is outbreeding in biology?
Outbreeding refers to matings between individuals from different populations, subspecies, or species. Outbreeding can result in a decline in reproductive fitness known as outbreeding depression, but this is less common than inbreeding depression.
What are the advantages and disadvantages of outbreeding?
Advantages of Outbreeding: Growth of more desired and a combination of characters. Disadvantages of Outbreeding: Outbreeding needs a transfer of gametes between persons. If individuals are far or if pollinators are in smaller amount then sexual reproduction may not occur at all in obligatory outbreeding species.
What are the benefits of outbreeding?
The general advantage of outbreeding is to promote an increase in phenotypic variability within a population. This generally enables plants to adapt to a wider range of environmental conditions and increases the likelihood for survival and evolutionary change.
What are the effects of in breeding?
The most obvious effects of inbreeding are poorer reproductive efficiency including higher mortality rates, lower growth rates and a higher frequency of hereditary abnormalities. This has been shown by numerous studies with cattle, horses, sheep, swine and laboratory animals.
How does outbreeding increase variation?
The second form of nonrandom mating is called outbreeding, wherein there is an increased probability that individuals with a particular genotype will mate with individuals of another particular genotype. Whereas inbreeding can lead to a reduction in genetic variation, outbreeding can lead to an increase.
Why is outbreeding bad?
Outbreeding can result in a decline in reproductive fitness known as outbreeding depression, but this is less common than inbreeding depression. ... Outbreeding between populations with chromosomal incompatibilities or those that are adapted to different environmental conditions can also increase extinction risk.
What is outbreeding with example?
2. Outbreeding is defined as being born to parents who are not related. An example of outbreeding is when two unrelated people have a child.
What causes outbreeding depression?
Evidence for outbreeding depression comes primarily from organisms with extremely limited dispersal, such as some plants, copepods, and scale insects; or from crosses between individuals from vastly different geographic sources; or with significant chromosomal differences.
Is outbreeding the same as inbreeding?
Hint: Inbreeding means mating of individuals of the same breed or of the closely related individuals. Outbreeding means mating of individuals from different populations, breeds, or species.
What is the effect of selective breeding on food crops?
Benefits of selective breeding
New varieties may be economically important, by producing more or better quality food, for example, larger tomatoes or drought resistant crops. Animals can be selected that cannot cause harm, for example, cattle without horns.
What is an effect of the agricultural practice of selective breeding?
By selectively breeding animals (breeding those with desirable traits), farmers increased the size and productivity of their livestock.
Is outbreeding a word?
The mating or breeding of distantly related or unrelated individuals. Crossbreeding is the most common form of outbreeding. ...
