Vedclass · Answer

(D) In pea plants,yellow seed color $(Y)$ is dominant over green seed color $(y)$.$A$ heterozygous yellow seeded plant has the genotype $(Yy)$.$A$ green seeded plant must have the homozygous recessive genotype $(yy)$.When these two are crossed: $(Yy) 	imes (yy)$.The gametes produced by the $(Yy)$ parent are $(Y)$ and $(y)$,while the $(yy)$ parent produces only $(y)$ gametes.The resulting offspring genotypes are $(Yy)$ (yellow) and $(yy)$ (green) in a $1:1$ ratio.Therefore,the ratio of yellow to green seeded plants in the $F_1$ generation is $50:50$ (or $1:1$).

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 $F_1$ generation?
