In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...
Micronuclei and Y Chromosome Loss: The formation of micronuclei, small cellular structures containing chromosomes or fragments, plays a critical role in the disintegration of the Y chromosome, linking ...
The male sex is determined by the presence of the Y chromosome, which contains a region of DNA that encodes a gene known as the sex-determining region of Y that promotes the formation of male gonads.
University of Virginia School of Medicine researchers have discovered a gene on the Y chromosome that contributes to the greater incidence of heart failure in men. Y chromosome loss in men occurs ...
Humans have 23 pairs of chromosomes, including a pair of sex chromosomes (typically XX for females, and XY for males). Chromosomes contain hundreds to thousands of genes, which are sections of DNA ...
A new paper published in Nature on June 4 shines light on how an enigmatic part of male aging—the loss of Y chromosomes—is connected with a higher risk of dying from cancer. In an analysis of 4,127 ...
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 Y chromosome can disappear over time in human males, which may introduce a number of health problems. While the exact trigger for such degeneration is unknown, environmental factors can play a ...
