Question

Explain model's monohybrid prgeny with the help of any one cross

Answer 1

Mendel's monohybrid cross

RR represents roundness of a pea pod and rr represents yellow colour of a pea seed.

                           RR   x    rr

                            ↓        ↓

                               R      r

                                  Rr     ⇒ F1 generation

                          Rr   x    Rr

                         ↓ ↓      ↓ ↓

                          R  r      R  r   on crossing

   RR         Rr         rR           rr   gametes  F2 generation

(round)    (round)  (round) (wrinkled)

phenotypic ratio: 3:1

genotypic ratio: 1: 2: 1
