You have guinea pigs from two pure breeding lines. One line has black fur and red eyes and the other line has white fur and blue eyes. When you cross them, all the F1 guinea pigs have black fur and blue eyes. When you cross the F1s to one another, you get a total of 50 F2 offspring. There are 31 with black fur and red eyes, 15 with white fur and blue eyes, 2 with white fur and red eyes, and 2 with black fur and blue eyes. There are approximately equal numbers of males and females in each phenotypic category.
