Question

3. In pea plants, inflated pods are dominant to constricted pods.

Answer 1

Answer:

Let's consider the alleles for a true- breeding inflated pod to be PP. Let's consider the alleles for the constricted pod to be pp. The punnet square for this can be shown as:

        p       p

P    Pp      Pp

P    Pp      Pp

The results from the punnet square show that there will be 100% (4:0) inflated pods offsprings produced from this cross. However, their genotype will be heterozygous.

A cross between the constricted pods can be shown as:

      p         p

p    pp      pp

p     pp     pp

The results from this cross show that the offsprings produced will be 100% constricted pod plants.
