Scientists published a full genetic sequence of the genes that make some white campions male, and hope their work could ...

People with shorter telomeres, the protective caps at the end of chromosomes (inside their white blood cells), may be more ...

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.

"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 ...

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 ...

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 ...

Allopolyploids are common in natural ecosystems (Grant, 1981). They arise as a result of distant hybridization (and chromosome doubling) between related species containing different sets of related, ...

The cells of female mammals randomly inactivate one X chromosome to keep gene dosage the same as in males. Does it matter which X becomes inactive? Surprisingly, it does, according to new research ...

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 ...

Chromosome abnormality is the condition in a cell or organism where the number of chromosomes or the structure of any chromosome differs from the normal karyotype. When the variant genotype is not ...

A team of Japanese scientists has discovered the gene that determines the fur color of calico cats, which are characterized by their white, black and orange (brown) coat. While it's been known ...
