Question

If the linked genes are present not very far off on the chromosome, the recombinant frequency would be ______. 

Options

• 50%

• less than 50%

• more than 50%

• 75%

Answer 1

If the linked genes are present not very far off on the chromosome, the recombinant frequency would be less than 50%.

Explanation:

Genes that are relatively close together are less likely to be separated by crossing over, so their recombination frequency is below 50%. A frequency of 50% indicates independent assortment.
