What is the example of a F2 generation??
Please find below the solution to the asked query:
The round shape and yellow colour of seed are dominant over the wrinkled shape and green colour seed. Mendel took round and yellow seed plants and crossed it with plants having wrinked green seeds.
A dihybrid cross between round and yellow seeds (RRYY) and wrinkled and green seeds (rryy) would be as follows;
Parents: RRYY x rryy
Gametes: RY and ry
F 1 generation: RrYy (Round and yellow)
F 2 generation: Self cross the plants of F 1 generation.
RrYy x RrYy
Gametes: RY, rY, Ry, ry (for both the parents)
For the second generation the punnett square is as follows:
|
Thus, the phenotypic ratio of round yellow: round green: wrinkled yellow : wrinkled green is 9:3: 3: 1.
