Male Sex Chromosome on Its Way Out: Study

But researchers believe a replacement will take over FRIDAY, July 17 (HealthDay News) -- Rapid evolution of the male sex chromosome could result in its disappearance within a few million years. But that won't mean the end of males, say U.S. scientists. Penn State researchers found t...

International Collaboration led by Dr. Pablo V. Gejman,Researcher At NorthShore University HealthSystem's Research Institute, Finds Genetic Association of Schizophrenia to Chromosome 6p Variant

CSHL scientists discover link between control of chromosome duplication and segregation

Cold Spring Harbor, N.Y. Before a cell can divide into two, first it must duplicate its genetic material--the DNA packed in its chromosomes. The two new sets of chromosomes then have to be separated from one another and correctly distributed to the resulting "daughter" cells, so that both daughte...
