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. If applicable, round off whole numbers. a. How many gene pairs are involved? b. What is the contribution of each additive allele to stripe length? cm c. How many skunks have 22 cm long stripe length? d. How many skunks have 20 cm long stripe length? e. How many skunks have 24 cm long stripe length? f. How many skunks have 26 cm long stripe length?
