if u don't mind just see. the pic

Answer 2

Answer:

Mendel is known as the father of genetics. He explains the concept of dominance, law of independent assortment and law of segregation.

The purple color flower (PP) is dominant over white flowers (pp). The purple flower can express itself in heterozygous condition as well. Their cross is as follows:

Parents   PP    ×      pp

Gametes   P     ×      p

F1 generation    Pp ( all purple flowers).

Selfing of F1 generation

Parents     Pp     ×     Pp

Gametes    P p  P  p

F2 generation  PP ( purple), Pp and Pp ( purple) and pp ( white).

The phenotype ratio is 3 ( purple) : 1 ( white)

The genotype ratio is 1 (PP) : 2 (Pp) : 1(pp).
