Y Chromosome

The y-chromosome doesn't recombine (most of it anyway), and forms a nested hierarchy of descent. ❋ Unknown (2010)

However, the male lineage and the female lineage each form a separate nested hierarchy as represented by the y-chromosome and the mitochondrial DNA respectively. ❋ Unknown (2009)

Sometimes even within species we can observe a nested hierarchy, such as the human y-chromosome, often used in genealogy. ❋ Unknown (2010)

With all that is known about genetic alteration, why not study the y-chromosome to find the "root of evil," so to speak? ❋ Unknown (2009)

If we turned, however, to science, to rout violence from human nature, it is possible to blame the y-chromosome, said to be the source of male violence. ❋ Unknown (2009)

Other great moments in thinking with your y-chromosome here and here. ❋ Unknown (2005)

So yes, the so-called “mitochondrial Eve” and “y-chromosome Adam” have been detected in cats, as well as in humans. ❋ Unknown (2007)

There was a time, not so terribly long ago, when genes which produced dark skin , or perhaps the lack of a y-chromosome, were considered 'less desirable.' ❋ Ann Althouse (2006)

The male calico has two x-chromosomes and a y-chromosome. ❋ Unknown (2006)

Being blessed with the genome of a successful political family, you can be certain that the y-chromosome wasn't the only piece of genetic information passed on by Papa "read my lips" Bush. ❋ Unknown (2006)

Might not ten thousand generations hence use the Bush y-chromosome as the genetic marker that signals a further branching of the genus Homo? ❋ Unknown (2006)

When in fact modern Egyptians have more African ancestry through their y-chromosome than modern Ethiopians do! their european features are not out of africa! ❋ Unknown (2010)
