Answer:

A) HT

Step-by-step explanation:

According to Mendel's law of segregation, the dominant and recessive alleles of a gene present together in a hybrid do not get mixed and are segregated to separate gametes during the process of gamete formation. Therefore, each gamete carries only one allele for a particular gene.

A hybrid genotype HhTt is heterozygous for two genes and therefore, will form a total of 2^2= four types of gametes in equal proportion. Each gamete has equal chances of getting either the dominant or recessive alleles of the mentioned genes. The genetic constitution of its gametes will be as following= 1 HT: 1 HT: 1 hT: 1 ht
