Answer:
37.5%
Explanation:
These here are
Black (AA or Aa) and albino (aa)
Agouti (Bb or BB)
Thus, a cross between
AaBb and aaBb
The percent of the progeny which are likely to be agouti would be
A. a. B. b
a. Aa. aa. B. BB. Bb
a. Aa. aa. b. Bb. bb
The probability of agouti would be
1/2 (Aa) * 3/4 (BB or Bb)
= 3/8
= 37.5%
