Members of a strain of inbred skunks whose stripes are uniformly 20 cm long are crossed to those of another strain whose stripes are uniformly 24 cm. The F1 hybrids all have stripes that are 22 cm long. When the F1 skunks were crossed, the F2 generation produced animals with stripes of 16,18,20,2224,26, and 28 cm. The 22 cm variety was the most frequent and the 16 and 28 cm varieties the least frequent. Of 1,000 skunks, 15 were 16 cm and 16 were 28 cm. NOTE: Enter numerical value answers.
