Question

Yellow pea color (A) is dominant to green pea color (a). Smooth pea texture (B) is dominant to wrinkled pea texture (b). If parent #1 is homozygous green and heterozygous smooth and parent #2 is homozygous yellow and homozygous wrinkled, what is the probability that the offspring will have yellow, smooth peas? Enter a number 0–100.

Answer 1

Answer:

50%

Explanation:

The genotype of the parent #1 who is homozygous green and heterozygous smooth would be= aaBb and that of the parent #2 who is homozygous yellow and homozygous wrinkled would be=AAbb. A cross between aaBb and AAbb would produce progeny in the following phenotype ratio=

1/2 yellow and smooth: 1/2 yellow and wrinkled.

Therefore, the probability that the offspring will have yellow, smooth peas is 1/2 or 50%
