Question

When a cross is made between round seed and yellow seeds (RrYy) and round seed and green seeds (Rryy), what proportion of phenotype in the offspring could be expected to be wrinkled and green

• A. $\frac{1}{8}$
• B. $\frac{1}{4}$
• C. $\frac{1}{2}$
• D. $\frac{1}{16}$

Answer 1

The correct option is A $\frac{1}{8}$

Gamete	Ry	ry
RY	RRYy	RrYy
Ry	RRyy	Rryy
rY	rRYy	rrYy
ry	Rryy	rryy

Since Yellow and Round seeds are dominant phenotypes, they are expressed in Heterozygous state.

Green and wrinkled seeds are expressed in recessive homozygous state, found only in rryy.

So, the correct option is 1/8.
