Solution

The correct option is C 9
Dihybrid F $_{1}$ - RrYy
Selfing of F $_{1}$ - RrYy x RrYy
Gametes - RY, Ry, rY and ry RY, Ry, rY and ry
RRYY RRYy RrYy RrYy
RRYy RRyy RrYy Rryy
RrYY RrYy
rrYY rrYy
RrYy Rryy rrYy rryy
The genotypes are: RRYY, RRYy, RrYY, RrYy, RRyy, Rryy, rrYY, rrYy and rryy.
Therefore, the correct answer is option C.
