New findings of researchers from the University of Modena and Reggio Emilia (Mauro Mandrioli, Valentina Monti and Gian Carlo Manicardi) show that in aphids the two X chromosomes have a different ...

Inheriting a normal and intact number of chromosomes in germ cells, egg and sperm, is essential for the preservation of all species. With increasing age, the risk of the egg cell not inheriting the ...

The findings reveal the biology behind segregation distortion, a phenomenon in which genes sway inheritance in their favor to beat the standard 50/50 odds predicted by Mendelian genetics. The team ...

(Dmitry Bayer/Getty Images) In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y ...

Centromeres act as the control centers of chromosomes, ensuring accurate genetic inheritance during cell division, yet they remain among the least understood genomic regions due to their repetitive ...

Duchenne muscular dystrophy (DMD) occurs as a result of genetic changes on the X chromosome. If someone has a gene change that can cause DMD, their children may inherit that change. DMD is a ...

Certain proteins may have evolved to tamp down 'cheating' during meiosis, the cell-division process that gives rise to eggs and sperm. While chromosomes can tip the scales in their favor of winding up ...
