In a cross between a black and a white guinea pig, all members of F1 generation are black. The F2 is made up of 10 black and 3 white guinea pigs. a) Using the correct gene symbol, diagram this cross up to F2 generation, showing the genotypes and phenotypes. b) What will the offspring be like if two F2 white guinea pigs are mated? c) What will the offspring be like if a F2 white guinea pig is back-crossed with a parent black guinea pig?
