Monohybrid Cross Problem Set
Problem 5: Another F1-hybrid cross
A genetic cross between two F1-hybrid pea plants having yellow seeds will yield what percent green-seeded plants in the F2 generation? Yellow seeds are dominant to green.
Among the F2 plants of a Yy x Yy cross, 25% will be yy with the recessive, green-seeded phenotype.
