Correct Answer

B

Explanation

This is the mating between unrelated or distantly related individual of a species. the individual are not closely related and thus are not genetically identical (have different genotypes). this type of selective breeding is important in agriculture where a type of crop or livestock possessing desirable trait is crossed with another variety with different desirable trait. the desirable traits of the two parents are combined in the offspring. the offspring have more resistant to adverse environmental conditions such as diseases or droughts. outbreeding combines favorable alleles from individuals and in this way maintain heterozygosity in the population, thereby masking recessive trait while dominant trait manifest. examples are mating between a donkey and a mule called beast of burden, and a cow and a buffalo to produce a cataloes.
