Answer:
They make trends in the data easier to see. They are easier to create than data tables.
Question no 1:
As mentioned in the question that parents are heterozygous for freckles (Ff).
Please see the punnet square in attached picture.
Question no 2:
As we can see in figure offspring will be as:
P1: Ff X Ff
F1: FF: Ff : Ff : ff
Phenotypic ratio: 3: 1
Genotypic ratio: 1: 2: 1
This is because freckles is a dominant trait and even one allele of dominant treat is enough to cause freckles to the offspring. However genotypically there is a difference between FF and Ff because the Ff will have lower chances to inherit the trait to offspring and FF will have more chances to transfer the trait to next offspring.
Hope it helps!
