Answer
c. increases with the distance between them
Work Step by Step
The probability of a crossover occurring between two genes on the same chromosome increases with the distance between them. This is a fundamental concept in genetics known as genetic linkage. The farther apart two genes are on a chromosome, the more likely it is that a crossover event will happen between them during meiosis. This is because there is a greater physical distance for crossing over to occur, as opposed to genes that are close together and are more likely to be inherited together without crossing over.
