Which of the following genotypes is heterozygous dominant?
bb
bbss
ttss
ss

Option D, Ss

Explanation:

A heterozygous dominant genotype consists of two different alleles of the same gene in which one is dominant allele and the other one is the recessive allele.

Symbolically the dominant allele is represented by the capital form of an alphabet and the recessive allele is represented by the small form of the same alphabet.

For example if "T" represents the dominant allele for tall height and "t"represents the recessive allele for small height, then Tt would represents a heterozygous dominant tall genotype. For a recessive allele to express there must be two copies of recessive allele for instance "tt"

Here among all given options , option D "Ss" is the correct answer
