Answer

Explanation:

Step1: Determine genotypes of parents

Homozygous green is yy, heterozygous yellow is Yy.

Step2: Set up Punnett - square cross

Y y
y Yy yy
y Yy yy

Step3: Analyze phenotypes

Yy is yellow, yy is green. 2 Yy and 2 yy, so 50% yellow and 50% green.

Answer:

A. 50 percent yellow, 50 percent green
