Probability of genotype TTrr in `F_(2)` generation of a dihybrid cross is

Options

A. `(1)/(16)`
B. `(1)/(4)`
C. `(1)/(6)`
D. `(2)/(16)`

Answer

A

Explanation

(a) In `F_(2)` gen. of dihybrid cross, the expected genotypic proportion of indivalduals having both the dominant alleles in homozygous condition is `1//16` and genotypic proportion of individual having both recessive alleles in homozygous condition is `1//16`.
