Question

Cross over value (COV) of gene A and B is 5% while COV of genes B and C is 15% the possible sequence of these genes on chromosome is:

• A. A – B – C
• B. C – A – B
• C. B – C – A
• D. Both (A) and (B)

Answer 1

The correct option is D

Both (A) and (B)

A – B – C or C – A – B
COV or cross over value is the percentage of linked genes that are exchanged during the process of crossing over, in the first prophase of meiosis.
