Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. what is the probability of having offspring that have wrinkled seeds and yellow seed color for the cross rryy ´ rryy?

The answer is 0 percent.

Let's represent alleles and genotypes:
R - dominant allele for round seeds,
r - recessive allele for wrinkled seeds,
Y - dominant allele for yellow seeds,
y - recessive allele for green seeds.

RR - dominant homozygote with round seeds,
rr - recessive homozygote with wrinkled seeds,
Rr- heterozygote with round seeds,
YY - dominant homozygote with yellow seeds,
yy - recessive homozygote with green seeds,
Yy * heterozygote with yellow seeds.

So, in order to have wrinkled seeds, the offspring's genotype must contain rr, and to have green seeds, the offspring's genotype must contain either YY or Yy.
According to the image, all of the offspring will have round, yellow seeds (RRYY, RRYy, RrYY, RrYy).
