The frequency of crossing over between two genes is dependent on the
A) size of each gene.
B) distance between the genes.
C) number of mutations in each gene causing disease.
D) genetic information coded in the genes.
E) number of alleles of each gene.

Question

Quizplus · Accepted Answer

The frequency of crossing over between two genes is dependent on their distance from each other on the chromosome. The farther apart they are, the more likely a crossover event will occur between them during meiosis. This is because there is more physical space for exchange to occur between them. The size of each gene, number of mutations causing disease, genetic information, and number of alleles do not directly affect the frequency of crossing over.
