Chromosomes can vary in length and size, but they usually carry thousands of base pairs of DNA. While scientists have successfully edited the genomes of many creatures, most of those edits have been ...

Most species on Earth exist as two biological sexes, and the exchange of genes between males and females is vital for their ...

Researchers from Skoltech, the University of Potsdam, and the Massachusetts Institute of Technology have discovered a ...

Transposons, or 'jumping genes' -- DNA segments that can move from one part of the genome to another -- are key to bacterial evolution and the development of antibiotic resistance. Researchers have ...

Researchers have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't produce enough ...

Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of sperm ...

The lab of developmental biologist Dr. Eric Lai has been studying evolutionary battles of the sexes in fruit flies. This colorful snapshot, courtesy of the Lai Lab, depicts sperm maturation in fruit ...
