Question

in a pae plant, the pink flower is dominant to blue. if a heterozygous pink flower crossed with blue flower plant, what ratio of pink and blue flower are in F1 generation​

Answer 1

The ratio of pink and blue flowers will be 1:1.

Explanation:

• A punnet square is a diagram which is made to check out the outcomes of a cross. Let's make a punnet square to check the outcomes of a cross between a heterozygous pink and homozygous blue flowered plant.

• The gametes for heterozygous pink will be P and p. The gametes for blue flower plant will be p and p.

                  P        p

          p     Pp       pp

          p     Pp       pp

• The results from above show that there is  50% chances for the F1 plant to either be heterozygous pink or homozygous blue.

• Hence, the ratio will be 1:1
