Hello!
Yellow = Y
Green = y
Based on the fact that 25% of the offspring inherited two recessive alleles (we know this because in order for a recessive allele to be expressed, it must be homozygous),<u><em> the parent peas had to both be heterozygous. </em></u>
Yy * Yy will always result in:
1/4 = yy
2/4 = Yy
1/4 = YY
I hope I helped!
