Explanation:
Detailed explanation-1: -The correct answer: The genotype which shows the character of homozygous dominant is D. SS.
Detailed explanation-2: -Explanation: A homozygous genotype means that you have two of the same alleles, which are represented by the letters A or a. So if an individual has AA or aa, we say they are homozygous.
Detailed explanation-3: -The recessive phenotype is controlled by the homozygous aa genotype. Therefore, the frequency of the dominant phenotype equals the sum of the frequencies of AA and Aa, and the recessive phenotype is simply the frequency of aa.
