Question

Tall plants are dominant to short plants. What are the genotype and phenotype ratios for a homozygous recessive female and a homozygous dominant male?

Answer 1

The genotype ratio for a homozygous recessive female (tt) and a homozygous dominant male (TT) is 0% tt and 100% Tt. The phenotype ratio for their offspring would be 100% Tall.

Step-by-step explanation:

In this case, the homozygous recessive female has a genotype of tt, whereas the homozygous dominant male has a genotype of TT. The phenotype is determined by the expression of the alleles, where Tall (T) is dominant over short (t).

Therefore, the genotype ratio for this cross would be 0% tt and 100% Tt.

As for the phenotype ratio, all the offspring would have the tall phenotype. So the ratio would be 100% Tall.
