<span>The genotype of the control bulls he should use to test for the heterozygous genotype is homzygous recessive. A creature can be homozygous dominant, on the off chance that it conveys two duplicates of a similar overwhelming allele, or homozygous recessive, on the off chance that it conveys two duplicates of a similar passive allele. Heterozygous implies that a living being has two unique alleles of a quality.</span>

When biogeographic isolation happen, the population of a certain species will be totally isolated (separated) from other species, which cause that population unable to cross-breeds with other species. This will form a unque and special species because that population will always maintain a certain characteristic unlike other population that are forced to cross-breed
