Chapter 14 #5 A black guinea pig crossed with an albino guinea pig produces 12 black offspring. When the albino is crossed with a second black one, 7 blacks and 5 albinos are obtained. What is the best explanation for this genetic situation? Write genotypes for the parents, gametes, and offspring Answer Albino (b) is a recessive trait; black (B) is dominant. First cross: parents BB ? bb; gametes B and b; offspring all Bb (black coat). Second cross: parents bb ? Bb; gametes 1/2 B and 1/2 b (heterozygous parent) and b; offspring 1/2 Bb and 1/2 bb #6
