India, March 17 -- Selfish chromosomes bias genetic inheritance by manipulating the overdrive (Ovd) gene, a natural sperm quality control checkpoint.

Germ cells pass DNA to the next generation and undergo massive reorganization of their DNA packaging to generate totipotency, or the ability to differentiate into any cell type. Understanding the ...

Scientists have identified an RNA-based sperm aging clock driven by rsRNA length changes, which may help assess paternal reproductive risk and offspring health.

Researchers often use a nematode worm called Caenorhabditis elegans (C. elegans) to study human genetics because at the molecular level, we have a lot in common with these organisms. Scientists used a ...
