short, white-furred short, brown-furred long, white-furred long, brown-furred 1/8 1/4 1/2 3/4 24 28 112 Cross the true-breeding short, brown-furred and long, white-furred guinea pigs to create an F1 population. Cross the F1 with their long, white-furred parent to produce backcrossed guinea pigs. The expected fur length and color in these guinea pigs should be 1/4 short, brown; 1/4 short, white; 1/4 long, brown; and 1/4 long, white. To increase the numbers of backcrossed progeny, cross two of the F1 males with their short, brown-furred mother (one at a time; the mothers have now mated the maximum of three times), thus producing 112 (amount) progeny. Then cross the long, white-haired male guinea pig with all of the short, brown-haired female F1, which would produce 144 progeny.
