Question

In a certain plant species, the allele for yellow seeds (Y) is dominant to the allele for green seeds. What is the phenotype result of a cross between a true-breeding yellow-seeded group of plants and a true-breeding green-seeded group of plants? A. all yellow seeds; no green seeds B. all green seeds; no yellow seeds C. 1/4 green seeds; 3/4 yellow seeds D. 1/4 yellow seeds; 3/4 green seeds @PinkFloyd

Answer 1

The answer is a because if u do a punnett square to get your results like i did, each plant would end up with the phenotype Y(yellow)y(green), and since they all have 1 dominant and 1 recessive, the dominant trait takes over, but the recessive trait is still there but it doesnt show up. 

hopefully my answer helps u
