Question

Determine the correct order of the genes on the chromosome, given the following information: Genes A and D cross over at a rate of 22% Genes A and L cross over at a rate of 5% Genes L and D cross over at a rate of 27%

Answer 1

Answer:

L-A-D

Explanation:

Given:

In crossing over percentage equals to map unit, so  22 %  equals to 22 map unit.

A and L are 6 map unit are closest one.

L and D are farthest away  and have 27 map unit distance.

A-D =22 map unit

A-L = 5 map unit

L-d = 27 map unit

so the sequence of genes is  L-A-D
