The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the biological sex, reproductive organs, and sexual characteristics that develop in a person.

Cephalopods may have the oldest sex chromosomes of any animal, according to a new discovery in the octopus genome. That's a big deal given that scientists didn't know until now if these oddball ...

Squamate reptile chromosome 2 (SR2) is thought to be an important remnant of an ancestral amniote super-sex chromosome, but a recent study showed that the Siamese cobra W sex chromosome is also a part ...

Summary: New research shows that female mice expressing only a maternal X chromosome experience faster brain aging and cognitive decline compared to those expressing both maternal and paternal X ...

But some plants have taken a different approach. They have evolved sex chromosomes, the bits of DNA that make individual plants either male or female. In that club are organisms like the ginkgo ...

Researchers at UC San Francisco found that female mice expressing only a maternal X chromosome experience faster brain aging and cognitive decline compared to those expressing both maternal and ...

"Given the fact that the X chromosome is enriched for brain-related genes, it became very important for us to know what roles it might be playing in brain aging," said Samira Abdulai-Saiku, Ph.D ...

Female mammals typically carry two X chromosomes — one from each parent — and a new study suggests that the maternal X is linked to faster brain aging. The X chromosome passed from mom to ...

Get Instant Summarized Text (Gist) The completion of the final synthetic chromosome in the yeast genome marks a significant advancement in synthetic biology. This achievement enables the creation ...

Triploid breeding based on unilateral sexual polyploidization is an effective approach for genetic improvement of Populus, which can integrate heterosis and ploidy vigor in an elite variety. However, ...
