In Mendelian dihybrid cross, when heterozygous Round Yellow are self crossed, Round Green offsprings are represented by the genotype

A

RrYy,RrYY and RRYy

B

Rryy, Rryy and rryy

C

rrYy and rrYY

D

Rryy and Rryy

Text Solution

Verified by Experts

The correct Answer is:
D
Heterozygous round yellow has the genotype RrYy. On selfing, round green offsprings are produced and are represented by Rryy and Rryy genotypes only (R= Round, yy= Green).
