A rather large population of foxes has 555 individuals with tan fur and 390 individuals with red fur. Assume that red is recessive.

Now that you have q, what should you solve for next?

• p

• q

• q²

• p²

A rather large population of foxes has 555 individuals with tan fur and 390 individuals with red fur. Assume that red is recessive. Calculate the following: 

1. The frequencies of each allele. 

2. The frequencies of each genotype.

3. How many foxes are of the heterozygous genotype?
