Many scientists agree that the universe is about 13 billion years old.
Answer:
<h2>C-A-B</h2>
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
