If the male is black (BB or Bb) and the female is brown (bb), then the possible genotypes of their offspring are Bb (black) and bb (brown). In order to produce 1/2 black and 1/2 brown offspring, the male must be heterozygous (Bb) and the female must be homozygous recessive (bb). Therefore, the best choice is Bb male and bb female.
