What are the resulting genotype or phenotype ratios

The rule of independent assortment states that alleles of one gene can segregate independently of alleles of other genes. In other words, the allele you pass on for one trait (for example, eye color) does not have any effect on the allele you pass on for some other trait (for example, height). Imagine you have conducted the following cross using a type of pea plant similar to Mendel.

P1 Round/Yellow (RR/YY)
P2 Wrinkled/Green (rr/yy)

a) What is (are) the phenotype(s) and genotype(s) of the F1 generation?

b) You cross the F1’s what are the resulting genotype/phenotype ratios of the offspring?
