The Frequency of Recombination During Meiosis Is a Function Of

The frequency of recombination during meiosis is a function of:

A) the alleles in the genes: recombination happens less frequently among recessive alleles.
B) the distance between genes: the closer the genes are, the more frequent the recombination between them.
C) the distance between genes: the farther apart the genes are, the more frequent the recombination between them.
D) whether or not the genes are sex-linked: genes in X chromosomes recombine much more frequently than do genes in the autosomes.
E) whether or not the genes are sex-linked: genes in Y chromosomes recombine much more frequently than do genes in the autosomes.
