Question

In a series of two point maps you find that genes A and B map at 30 map units apart, A and C map at 15 map units apart and B and C map at 45 map units apart. What is the correct order of the genes?

Answer 1

C-A-B

Step-by-step explanation:

Given

As given: A and B are 30 map unit apart

A and C are 15 map unit apart

B and C are 45 map unit apart

So the sequence of genes : according to the map unit distance is:

C-A-B

C-15-A-30-B

C-A=15

A-B=30

C-B= 45.

correct order of genes is C-A-B .
