In pea plants, yellow seeds (Y) are dominant to green(y) and round seeds (R) are dominant to wrinkled (r) . A cross was done between two pea plants of the P generation that were BOTH yellow round seeds to produce these 200 offspring in the F1 generation 150 yellow round and 50 yellow wrinkled.

What are the dihybrid genotypes (for both Y/y and R/r) of the P generation plants?(Hint for this problem i do not think I need to use a full dihybrid cross.

One half of one of the parents genotypes will come out to something like "A " one allele is unknown
