Answer:
The correct answer is option C.
Explanation:
As it is given that, a Mendelian cross is performed between two parents resulted by cross the parents. This suggests that the parents or P generation has zero recombination hence the genotype of Parents would be AA and aa in nature. Therefore, all the F1 generation offspring were Aa in nature. The selfing of the F1 offspring will be:
A a
A AA Aa
a Aa aa
Genotype: AA: Aa: aa :: 1:2:1
Phenotype: Dominant: recessive :: 3:1
