What is the relationship between the degree of crossing over and the distance between two genes?
A)There is no correlation.
B)It is direct: as the distance decreases,the frequency of recombination increases.
C)It is indirect: as the distance decreases,the frequency of recombination doubles.
D)It is indirect: as the distance increases,the frequency of recombination doubles.
E)It is direct: as the distance increases,the frequency of recombination increases.

The relationship between the degree of crossing over and the distance between two genes is direct, meaning that as the distance between two genes increases, the frequency of recombination also increases. This is due to the fact that the further apart two genes are located on a chromosome, the greater the chance that multiple crossovers will occur during meiosis, which can result in an increased frequency of recombinant gametes. Therefore, Choice E is the best choice.
