About the X-to-Y Gene Conversion Rate [PDF]

open access: yesThe American Journal of Human Genetics, 2010
To the Editor: It has long been accepted that productive recombination between X and Y chromosomes in humans is limited to short telomeric portions known as pseudoautosomal regions. It now appears that our picture of X-Y chromosome recombination requires revision because of the observation that gene conversion between X and Y gametologous regions ...
