The X chromosome carries at least 150 genes linked to intelligence. Since the mother has two X chromosomes to pass along while the father only has one, the mother’s contribution to the child’s ...

For chromosomes to form the iconic X-shape that ensures the accurate passing of genetic information during cell division, a ...

How could this trait be explained? And did this fly disprove the basic premise of the chromosome theory? In the Morgan lab's search to make sense of the white-eyed female, Lilian Vaughn Morgan ...

it is highly condensed and wrapped around histones in order to fit inside of the nucleus and take part in the formation of chromosomes. Histones are basic proteins, and their positive charges ...

"We're diving into the basic science of how sex chromosomes influence not just how disease develops, but how cells respond to treatment," said Aguado. "By figuring out these sex-dependent ...

In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.

Aneuploidy and its consequences on the cell Aneuploidy, a state where cells have an incorrect number of chromosomes, is ...

World Down Syndrome Day: Down syndrome appears as a genetic disorder following abnormal cellular division which results in either an entire or partial additional chromosome 21. The body and brain ...

To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell division, each chromosome forms a compact X-shaped structure with two rod-like copies. How the cell ...

Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the dormant X get "reawakened" later in life, potentially giving the brain a boost.

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.
