If two genes are far apart, for example at opposite ends of the chromosome, crossover and non-crossover events will occur in equal frequency. Genes that are closer together undergo fewer crossing over events and non-crossover gametes will exceed than the number of crossover gametes.
It follows that: • the probability of a crossover between two genes is proportional to the distance between the two genes. That is, the greater the distance between the two genes, the greater the probability that a crossover will occur between them during meiosis.
Does crossing over increase with distance?
The frequency with which crossing over occurs between any two linked genes is proportional to the distance between them. … in other words, as the distance between two genes increases, the probability that a crossover will occur between them also increases.
