Marthe Gautier, découvreuse oubliée du chromosome de la trisomie 21

Marthe Gautier est à l’origine de la découverte du chromosome surnuméraire de la trisomie 21, anomalie génétique qui touche 50 000 personnes en France. À l’occasion de la Journée mondiale de la trisomie 21, retour sur le parcours de cette scientifique invisibilisée, avec la biologiste Julie Batut.

Although a low level of #Neanderthal ancestry is present in most #humans, the Neanderthal genes are not uniformly distributed.

A handful of regions in the #autosome are entirely devoid of such ancestry in essentially all living humans, and the X #chromosome is strongly depleted across its sequence.

These patterns are most consistent with Neanderthal contributions to human populations being heavily male biased.

The interbreeding between the two groups was predominantly that of male Neanderthals with females of the anatomically modern human population.

#KnowledgeByte: The Y #Chromosome is shrinking and losing genes over millions of years, a process called genetic degeneration, with estimates suggesting it could vanish in 10-11 million years.
