In pea plants, seed shape and seed color are controlled by genes located on different chromosomes. seeds may be round (r) or wrinkled (r), with the allele for round seeds being dominant. alleles for seed color are yellow and green, with the green allele (y) recessive to the yellow (y) allele. if you cross an individual that is homozygous round and yellow with an individual that is homozygous for wrinkled and green, what is the genotype of the f1 individuals? set up a punnett square for the dihybrid cross.
