In mice, the allele for black fur is dominant to the allele for brown fur.
Xelga [282]

Answer:

50%

Explanation:

The allele for black fur (B) is dominant to the allele for brown fur (b).

  • BB or Bb = black fur
  • bb = brown fur

A male homozygous black mouse (BB) is crossed with a female brown mouse (bb). The male parent only produces<em> B</em> gametes and the female parent only produces <em>b</em> gametes. The F1 offspring will be 100% heterozygous Bb.

The F1 individuals will produce <em>B</em> and <em>b</em> gametes. If we cross the F1 individuals to each other (Bb x Bb), we'll get the following F2 offspring:

  • 25% BB homozygous dominant
  • 50% Bb heterozygous
  • 25% bb homozygous recessive

So 50% of the F2 will be homozygous (BB or bb).
