The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

(Image: National Human Genome Research Institute) Chromosomes contain the genome, the complete set of genetic instructions for an organism. The DNA within the chromosomes encodes genes, which are the ...

UCSF researchers found that brain cells age more quickly when they rely solely on the X chromosome inherited from a female's ...

However, the large chunk that has been sequenced contains versions of several of the same genes that are found in the modern human Y chromosome. In modern humans, a Y chromosome gene called SRY ...

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don’t ...

What makes the Y chromosome so special (despite having far fewer genes than its X counterpart) is that it contains the SRY ...

Researchers at Linköping University in Sweden made an unexpected discovery while investigating genetically unique women.

A high-quality genome assembly of Silene latifolia was generated by researchers at CNRS/Université Claude Bernard Lyon 1 and ...

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

Each gamete contains a single copy of every chromosome, and each chromosome contains one allele for every gene. Therefore, each allele for a given gene is packaged into a separate gamete.

However, there is some evidence that the Y chromosome is being phased out of the evolutionary pipeline, and could one day disappear altogether — potentially giving rise to a new sex gene in the ...
