Researchers from Johns Hopkins University and the University of Copenhagen analyzed over 139,000 embryos and identified variants in key meiosis genes, such as SMC1B, that influence chromosomal ...

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 ...

There is a high unmet need for accessible, affordable, and high-quality fertility care, as approximately 1 in 6 people are affected by infertility worldwide. While meiotic failure is a major cause of ...

Human genetic diversity wouldn't be possible without DNA crossovers in egg and sperm cells. Two studies provide new insights into how crossovers go right -- and wrong, leading to infertility, ...

A research team at The University of Osaka has found a novel pathway for depositing CENP-A into vertebrate centromeres, which ...

Despite the immense amount of genetic material present in each cell, around three billion base pairs in humans, this material needs to be accurately divided in two and allocated in equal quantities.
