1.What is the genotype for short plants?
2.What is the genotypic ratio?
(Your answer should include # genotype : # genotype.)
3.What is the phenotypic ratio?
(Your answer should include # phenotype : # phenotype.)
4.In this example, for which kind of plant (Tall or short) do you know its genotype just by looking at the plant? and why? (4 pts.)

-
T = allele for tall plants
t = allele for short plants
1. tt
2. I do not know because the data is not given. If generation P is two pea plants, TT and tt, then the F1 generation would all be 0:1:0 (TT:Tt:tt). The F2 generation would be 1:2:1 (TT:Tt:tt). See the Punnett square in the Sources section.
3. F1 would be 1:0 (Tall:short) and F2 would be 3:1.
4. For the short plant, you know its genotype just by looking at the plant because only a genotype of tt produces the short phenotype.
