It is known that fur color in pigs is determined by the Parva gene. Pigs of a normal pure wild breed have gray fur. In a special farm for raising pigs in Japan, there is a breed with yellow fur. The Purebred females with yellow fur were crossed with wild purebred Japanese males with gray fur (generation P). 1000 offspring were obtained in generation F1, and 999 of those offspring (males and females) have yellow fur, and 1 offspring is a male with gray fur. Students were asked to offer possible explanations for the event that caused the appearance of the special male (with gray fur) in the F1 generation. A student came up with a possible explanation for the event that caused the appearance of the special male in the F1 generation. According to the student's hypothesis, in the hybridization between this special male and a normal grey pure wild breed female, all the offspring (F2) will have gray fur. A. Explain what the student's hypothesis was and why, according to her hypothesis, all the offspring will be Gray. B. Offer another explanation for the appearance of the special male and write what will be the results of hybridization between the special male and a female of the normal gray pure wild breed.
