The planned changes include reinstating a version of chromosome testing that was discontinued in the 1990s, requiring athletes who compete in the female category to submit to a cheek swab or dry blood ...

The Lycosidae family, known for its diverse spiders with varying ecological habits and behavioral traits, has seen limited exploration of its karyotype and genome size. Methods: We utilized an ...

Scientists at EMBL have captured how human chromosomes fold into their signature rod shape during cell division, using a groundbreaking method called LoopTrace. By observing overlapping DNA loops ...

Genders can be distinguished according to the sex chromosome karyotype, gonadal structure, external genital organ shape, and secondary sexual characteristics. According to the morphology of the vulva, ...

Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the dormant X get "reawakened" later in life, potentially giving the brain a boost.

This important study capitalizes on the sophisticated genetics available in the Drosophila system and uses a combination of methodologies to start to tease apart how polyphosphate participates in ...

This study provides valuable insights into the complex genetics of dominant optic atrophy. Leveraging a fly model, the investigators provide solid evidence, albeit with small effect sizes, for a ...
