Vedclass · Answer

(A) Let the allele for yellow seeds be $Y$ and the allele for green seeds be $y$. Since yellow is dominant,the genotype for a heterozygous yellow-seeded plant is $Yy$. The genotype for a green-seeded plant (recessive) is $yy$. Performing the cross: $Yy 	imes yy$. The gametes produced are $Y$ and $y$ from the heterozygous parent,and $y$ from the green-seeded parent. The resulting offspring genotypes are $Yy$ (yellow) and $yy$ (green) in a $1:1$ ratio. Therefore,the expected ratio of yellow to green-seeded plants is $1:1$.

In pea plants,yellow seeds are dominant over green seeds. If a heterozygous yellow-seeded plant is crossed with a green-seeded plant,what will be the expected ratio of yellow to green-seeded plants in the $F_1$ generation?
