Use a punnett square to predict the offspring in a cross between a dwarf pea plant (homozygous recessive) and a tall pea plant (heterozygous). what is the phenotypic ratio of the offspring?

Tall : dwarf is 1:1

Explanation:

Let "T" represents the allele for a tall pea plant

while "t" represents the allele for a dwarf pea plant

Here "t" is  recessive allele.

Genotype of dwarf pea plant (homozygous recessive) - tt

Genotype of tall pea plant (heterozygous) - Tt

A punnet square showing the cross between tt and Tt is given below-

Tt

tTttt

tTttt

Phenotypic ratio -

Tall : dwarf

Tt: tt

2:2

1:1
