WebNov 15, 2016 · Sex chromosomes are chromosomes that determine whether the individual is male or female. Though these two chromosomes pair with each other during meiosis, there is usually very minimal homology or recombination between them, primarily because of a large difference in their genetic content and size. WebWhen genes are close together on the same chromosome, they are said to be linked. That means the alleles, or gene versions, already together on one chromosome will be …
