In pea plants tall T is dominant over short t What is the ge

In pea plants, tall (T) is dominant over short (t). What is the genotypic and phenotypic ratio of the offspring resulting in a cross between a Tt and a Tt plant?

Genotypic Ratio _________           Phenotypic Ratio ___________

(TT:Tt:tt)                                           (TT + Tt) : tt

In pea plants, tall (T) is dominant over short (t). What are the genotypes and phenotypes of the offspring of a cross between a homozygous tall pea plant and a short pea plant?

Genotype____________               Phenotype___________

Genotypic Ratio _________           Phenotypic Ratio ___________

Solution

1). Cross between Tt and Tt will have the progeny with the following genotypes and phenotypes:

Tt* Tt ----> TT(1/4, tall), Tt (1/2, tall), tt (1/4, short)

Thus, the genotypic ratio of TT:Tt:tt is = 1:2:1

The phenotypic ratio (tall:short) is, 3:1.
