In pea plants, yellow seeds are dominant to green. If a heterozygous yellow seeded plant is crossed with a green seeded plant, what ratio of yellow and green seeded plants would you expect in F1 generation?

Question

Accepted Answer

50 : 50. A heterozygous yellow plant has genotype Yy, and a green plant must be yy. Crossing Yy × yy produces offspring that are half Yy (yellow) and half yy (green), so the phenotypic ratio is 50:50.
