Explanation:
Detailed explanation-1: -Answer and Explanation: The correct answer: The genotype which shows the character of homozygous dominant is D. SS.
Detailed explanation-2: -The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive. In contrast, the term “heterozygous” is used to describe the allelic pair, “Aa”.
Detailed explanation-3: -A homozygous recessive genotype, as mentioned above, has two recessive alleles. In genetics, this is designated with two of the same lower case letters such as aa.
