Which of the following statements is not true of two genes that show 50% recombination frequency?
A
If the genes are present on the same chromosome, they undergo more than one crossovers in every meiosis
B
The genes may be on different chromosomes
C
The genes are tightly linked
D
The genes show independent assortment
Detailed Solution
A 50% recombination frequency means the genes assort independently: they are on different chromosomes or very far apart on the same one.
Tightly linked genes show very low recombination, so that statement is not true.
Tightly linked genes show very low recombination, so that statement is not true.
