describe the f1 and f2 genotypic and phenotypic ratios resulting from a cross between a tall and a short plant

Answer 1

A heterogenous tall plant is TT and a short plant is tt. A heterogenous Tt plant is also tall.

f1 is easy. Every plant is a Tt hybrid, which is heterogenous tall. There are no ratios, because there is just one genotype and one phenotype.

In f2, genotypically you have 1/4 TT, 1/2 Tt, and 1/4 tt. (You can see this if you set up a Punnet square with both parents being Tt.) Thus, the ratio of TT:Tt:tt is 1:2:1. Since the TT and Tt are both genotypes for the tall phenotype, the phenotypic ratio of tall:short is 3:1.

Answer 2

F1 = a hundred% tall Dd F2 = seventy 5% tall (25p.c.DD, 50% Dd) 25% short (dd) while you're predicted to try this on an examination it would be nicely worth working in the direction of on your guy or woman too! we can't come help you throughout a attempt. that is typically solved making use of a punnet sq..
