A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits.
a pea plant -homozygous and dominant for round (RR), yellow (YY) seeds and a pea plant homozygous and recessive for wrinkled (rr), green (yy) seeds.
RRYY x rryy
F1 generation: all heterozygous plants with round, yellow seeds and the genotype RrYy.
Self pollination of F1 generation
RrYy x RrYy
F2 progeny -9:3:3:1 ratio and produces
nine plants with round, yellow seeds,
three plants with round, green seeds
three plants with wrinkled, yellow seeds
one plant with wrinkled, green seeds.
Hope it helps!
