Question

1. Imagine a mother and a father who both have freckles and are heterozygous for the trait, or Ff. They are theP generation, or parent generation. Create a Punnett square to show their offspring, the F1 generationAnswer:Part 1 Punnett Square

Answer 1

As the task sais both parents are heterozygous, therefore it is expressed (Pp x Pp).

The Punnett square is useful to see the different possible combinations of the alleles in their offspring.

To create the Punnett square we first draw the square:

Then we do the possible combination by completing the square:

As shown in the square the possible combinations are:

PP, Pp, Pp and pp.

In this case 3 out of 4 offspring will show the trait (freckles)
