heterozygous
|
|
|
hybrid
|
|
|
dominant
|
|
|
homozygous
|
Explanation:
Detailed explanation-1: -Homozygous, as related to genetics, refers to having inherited the same versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is homozygous for a genomic marker has two identical versions of that marker.
Detailed explanation-2: -Individuals carrying two identical alleles (RR or rr) are known as homozygous.
Detailed explanation-3: -When the loci in the matching chromosomes bear the same alleles, it is described as homozygous. It means that the alleles code for the same trait. A ‘homozygous’ organism for a particular trait is described to possess either a pair of dominant alleles (e.g. AA) or a pair of recessive alleles (e.g. aa).
