The Principle of Segregation describes how pairs of gene variants are separated into reproductive cells. The segregation of gene variants, called alleles, and their corresponding traits was first ...

According to several authors cranio-cerebello-cardiac (3C) syndrome is an autosomal recessive disorder. This opinion was based on pedigree inspection without formal segregation analysis. Recently, the ...

It is hard to resist anthropomorphizing selfish genes, particularly when they appear to defy the rules of natural selection, sweeping through populations despite conferring little or no survival ...

Researchers from UConn and other institutions in the U.S. and abroad have shown how a relatively young gene can acquire a new function and become essential to an organism's life. Using a combination ...

A mathematical model provides new insights into the distribution of genetic information during bacterial cell division The precise segregation of DNA and the faithful inheritance of plasmids are ...

The human genome is littered with "selfish genetic elements," which do not seem to benefit their hosts, but instead seek only to propagate themselves. Selfish genetic elements can wreak havoc by, for ...

CHAPEL HILL, NC - R2d2 is selfish. It is a true selfish gene. It propagates itself through generations but not for some evolutionary advantage. Quite the opposite. Research led by UNC School of ...

Copies of the mouse gene R2d2 can spread quickly through lab and wild mouse populations, despite the fact that the genes cause females to have fewer offspring. This is the first time scientists have ...
