In goats, the gene for coat color is on an autosome and light brown color is dominant to black. A light brown male is mated to a black female, producing a black kid (baby goat). If they produce another kid, could it be light brown? If so, what are the chances of it being light brown?
A. No, since the black allele is present all offspring will be black
B. Yes, 100% since the first kid was black the next one has to be light brown
C. Yes, 75% since light brown is dominant
D. Yes, 50% as the male must be heterozygous for color
E. Yes, but it will depend on whether the kid is male or female
D. Yes, 50% as the male must be heterozygous for color
