In a dihybrid cross for round and yellow seeds (RrYy x RrYy), what is the probability of having green and wrinkled seeds?
Virty [35]

Answer:

The probability of having green and wrinkled seeds is equal to 6.25%

Explanation:

Here R allele is dominant over r allele and Y  allele is dominant over y allele.

Thus, a green phenotype will have genotype rr

and a wrinkled phenotype will have genotype yy

The punnet square representing the cross between RrYy  and  RrYy is as follows -

RY         Ry         rY         ry

RY RRYY RRYy RrYY RrYy

Ry RRYy RRyy RrYy Rryy

rY RrYY RrYy rrYY rrYy

ry RrYy Rryy rrYy         rryy

Out of all 16 offspring, only one offspring with genotype "rryy" represents green and wrinkled seeds.

Thus,  the probability of having green and wrinkled seeds is equal to

\frac{1}{16} * 100\\= 6.25%
