Question

A Pure inflated pol pea plant is crossed with
Pure constricted lod Pea plant dihybrid cross​

Answer 1

Explanation:

Dominant trait- Inflated pod shape P

Recessive trait- Constricted pod shape p

P PP x pp

P P p p (gametes produced)

F1 Pp x Pp (self-fertilization)

P p P p (gametes produced )

F2 P p

P PP Pp

p Pp pp

The phenotypic ratio for F2 is 3:1

where 3 is individuals showing the dominant trait and 1 is an individual showing recessive trait.

The genotypic ratio for F2 is 1:2:1
