Problem:
You have three guinea pigs: white, orange, and brown. You wanted to make some crosses to determine inheritance pattern for coat color.
Question: Assume that one gene is responsible for coat color.
(P) Orange X (P) white = (F1) 1 Red : 1 Yellow
(F1) Red X (F1) red = (F2) 3 red : 1 white
(F2) White X (P) Brown = (F1) 1 brown : 1 white
(F1) Brown X (F1) Brown = (F2) 3 brown : 1 white
(P) Orange X (P) Orange = 1 red : 2 orange : 1 yellow
(P) Brown X (P) Orange = 1 red : 1 yellow
Required:
Question 1: Based on these results, what are the genotypes of these guinea pigs? Make sure to show the Punnet squares for each individual cross listed above
Question 2: You cross an Orange guinea pig with a (F1) yellow guinea pig. What is the probability that out of 5 offspring, 3 are orange? Justify your answer.
