Having two of the same allele
What is homozygous?
Brown (B) is dominant fur over silver-blue fur (b) in minks. If a homozygous brown mink is mated with a silver-blue mink, and 10 offspring are produced, how many will be expected to be silver-blue? Why?
0 because in order to be silver-blue, two b alleles have to be inherited.
