Rob Stein http://wgcu.org en With Men's Y Chromosome, Size Really May Not Matter http://wgcu.org/post/mens-y-chromosome-size-really-may-not-matter Basic biology has it that girls are girls because they have two X chromosomes — the things inside cells that carry our genes. Boys are boys because they have one X and one Y. Recently, though, there's been a lot of debate in scientific circles about the fate of that Y chromosome — the genetic basis of maleness.<p>Very early in the evolution of the Y chromosome, explains <a href="http://wi.mit.edu/people/faculty/page">Dr. David Page</a>, a geneticist at the Massachusetts Institute of Technology, something pretty dramatic happened: The ancestral Y lost most of its genes.
