Repeat the process again when one parent is heterozygous black and the other is homozygous brown.
Genotypes:
% homozygous black fur (BB)
% heterozygous black fur (Bb)
% homozygous brown fur (bb)
Phenotypes:
% black fur
% brown fur

genotypes:

0% homozygous black fur (BB)

50% heterozygous black fur (Bb)

50% homozygous brown fur (bb)

phenotypes:

50% black fur

50% brown fur

Explanation:

   B b

b . Bb bb

b . Bb bb
