Explanation:

So the capital letter is the dominant trait, and the lowercase letter is recessive. The capital dominant trait will always overpower the lowercase recessive trait. So the only way the recessive trait can be seen is if there are two together. So... if R is white fur and r is brown fur...

RR would show the dominant trait of white fur

Rr would show the dominant trait of white fur

rr would show the recessive trait of brown fur
