Find the given answer- Heredity Class 10

Solution:
Consider the following cross in order to understand the genotype and phenotype of the F1 generation:

(a) As per the dihybrid cross shown above, the phenotype of F1 generation in Round and Yellow Seeds.
(b) The genotype of parent generation is RrYy
(c) If a plant with wrinkled and green seeds (rryy) is crossed with a plant with wrinkled and yellow seeds (rrY_), the offspring will be wrinkled and yellow seeds. 
(d) The result of self pollination of YyRr plant is explained above with the help of cross. We will obtain Phenotypic ratio 9:3:3:1

Round yellow 9

Round green 3

Wrinkled yellow 3

Wrinkled green 1
