Question

In pea plants, the gene for the color of the seed has two alleles. In the following Punnett square shown below, the dominant allele (Y) represents yellow and the recessive allele (y) represents green.

Based on the Punnett square, what percentage of offspring would be expected to have yellow seeds?

0%

25%

50%

100%

Answer 1

Answer: The answer is 0%

Explanation: I took the pre-test.

Answer 2

100% of the seeds will be yellow

Step-by-step explanation:

This is because you will have "YY", "Yy", "YY" and "Yy". The genotypes "YY" are dominant and the genotypes "Yy" are dominant recessive therefore you will have a 100% chance of having all yellow seeds.
