Mendel's dihybrid crosses PDF results

What about two traits? dihybrid crosses

What about two traits? dihybrid crosses! consider two traits for pea:- color: y (yellow) and y (green)- shape: r (round) and r (wrinkled)! each dihybrid plant produces 4 gamete types of equal frequency.- yyrr(adult) " four gamete types: yr, mendel's laws law of dominance: in a cross of parents that are pure for different traits, only one form of the trait will appear in the next generation.
