Answer:
First thing you need to do is get the alleles of the mother and father. They are heterozygous dominant for freckles, their genotypes are Ff. Your Punnett would look like this:
P generation cross: Ff x Ff
F f
F FF Ff
f Ff ff
Looking at the Punnett, just list all the possible genotype combinations, then count how many you see in the Punnett. But when you tlak about phenotype, you will be looking at what was expressed. Since Freckles are dominant, when there is at least 1 dominant allele in the combination, the dominant trait will be expressed.
Genotype Number Phenotype
FF 1 Freckles
Ff 2 Freckles
ff 1 No Freckles
You can see that FF and Ff will both express freckles, so you add up their ratio.
Based on this:
genotype ratio would be 1 FF: 2 Ff: 1 ff or 1:2:1
phenotype ration would be: 3 Freckles: 1 No freckles or 3:1
