QUESTION:
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 outcome? Write genotypes for the parents, gametes, and offspring.
ANSWER:Step 1 of 3
Assume that coat color in guinea pigs is determined by a single gene, with black (B) being dominant and albino (b) being recessive. The genetic outcomes can be shown through the Punnett square.
