Question

Explain how these tail lengths were inherited by describing the mode of inheritance, indicating how many gene pairs were at work, and designating the genotypes of Harvey, Irma, and their 18- cm -tail offspring. Drag the terms on the left to the appropriate blanks on the right to complete the sentences.

Answer 1

Here we can see that 7 phenotypes appeared in F2 generation, so the number of genes involved is 3 and alleles is 6. Contribution per allele = 4 cm Base contribution = 6 cm

Genotype of Harvey = aa bb cc Genotype of Erma = AA BB CC

Number of dominant alleles if length is

18 cm = 18-6 / 4 = 12 / 4 = 3.

F1 generation genotype = Aa Bb Cc This clarifies why the length is 18 cm, as there are three dominant alleles.

seven 1. It is likely that there are gene pairs in this cross. There are

categories of phenotypes. The genotypes of the parents would be combinations of alleles that would produce a 6 cm ( aabbcc ) tail and a 30 cm) tail, whereas the 18 cm offspring would have a genotype of AaBbcc.
