#chromosome — Public Fediverse posts

“evolutionary #genome topology compares genome architecture rather than only DNA sequence, it gives researchers a way to turn the growing flood of #chromosome -scale animal genomes into a shared coordinate system.”

Yes: Macroevolution is not microevolution, and genomes are not "bags of genes".

Animal genomes follow irrevers...

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.

So it should be noted that a new definition is needed — NeanderthaL is asking for it.
and

And not only him: consider the rare cases of fertile mules, rare but not conceptually marginal.

In the published document an extreme case is mentioned: an unicorn.
Suppose it is born among horses — could donkeys inherit it too?
And zebras?

#KnowledgeByte: The Y #Chromosome plays a crucial role in determining the sex of a baby.

It is also very important to study the genetic history of different populations and the evolutionary history of mammals and to understand the process of sex determination.

I think #MAGA people like #CharlieKirk because he looks like he's missing a #chromosome from #inbreeding, just like them.

Researchers found that compared with the group taking the placebo, those taking vitamin D supplements had reduced telomere shortening over four years. Omega-3 fatty acid supplementation, on the other hand, had no obvious effect on telomere length.
