The phenotypic ratio in the offspring when we cross a heterozygous plant to a recessive plant of pean plants tall (T) as dominant to short (t) as recessive is 3:1.
The phenotypic ratio in the offspring when we cross a heterozygous plant to a recessive plant of pean plants tall (T) as dominant to short (t) as recessive can be calculated as follows?
P1 : TT x tt
F1 : Tt
P2 : Tt x Tt
F2 : TT, Tt, Tt, tt
Based on the calculation above we can see that the number of pea plants gamete cells tall (T) dominant is 3, and the number of pea plants gamete cells short (t) is 1.
Hence, the phenotypic ratio in the offspring is 3:1.
