Question

1. this diagram shows a punnett square illustrating the possible offspring from a cross between two pea plants heterozygous for flower color. what is the percentage chance of these two parents producing heterozygous dominant offspring? 100% 25% 50% 75% clear all

Explanation:

Step1: Count heterozygous offspring

In the Punnett square, the genotypes are PP, Pp, Pp, pp. Heterozygous (Pp) offspring count: 2.

Step2: Total offspring count

Total number of offspring (squares): 4.

Step3: Calculate percentage

Percentage = $\frac{\text{Number of heterozygous}}{\text{Total offspring}} \times 100\%$ = $\frac{2}{4} \times 100\%$ = $50\%$.

Answer:

50% (corresponding to the option with "50%")
