A tall, heterozygous pea plant is cross-pollinated with another tall, heterozygous pea plant. Use a Punnett square to determine the probability that the offspring is a tall, homozygous pea plant.(1 point) Responses 75% 75% 50% 50% 0% 0% 25%
The Punnett square for this cross is:
T t
T TT Tt
t Tt tt
In this Punnett square, the offspring can be TT, Tt, Tt, or tt.
Out of these four possibilities, only one of them (TT) represents a tall, homozygous pea plant.
Therefore, the probability that the offspring is a tall, homozygous pea plant is 25%.
