If a male genotype is tt and the female genotype is tt, then what are the phenotypic ratios for tall and short corn? phenotype : a. short b. all tallc. tall d. all short

The correct answer is b. all tall

Explanation:

If the genotype of one parent for height is Tt and another parent is TT then after the fusion of gamete all the offspring will show tall phenotype because all the offspring will have at least one allele of tall character.  

                     T    t

               T   TT  Tt

               T   TT  Tt

So after cross two phenotype would be homozygous dominant for tall character and the other two will be heterozygous dominant for tall character. Therefore all the offspring would be tall.
