How are homologous chromosomes defined?

In meiosis X and Y chromosomes will pair as homologous chromosomes but will recombine only in a few limited re?

  • Answer:

    The human Y chromosome is unable to recombine with the X chromosome, except for small pieces of pseudoautosomal regions at the telomeres (which comprise about 5% of the chromosome's length). These regions are relics of ancient homology between the X and Y chromosomes. The bulk of the Y chromosome which does not recombine is called the "NRY" or non-recombining region of the Y chromosome Read more: http://www.answers.com/topic/y-chromosome#ixzz1qWNwv9JQ

Recombination can only occur in those very short regions where the X and Y contains the same genes - because those are the only places that pair up.

They have regions of homology that are enough to allow them to pair up during meiosis.
