The Y chromosome is inherited only through the paternal line. Sons receive their Y chromosome exclusively from their father.

X chromosome reactivation contributes to reducing the signs of disease in the female brain. Female cells have two X ...

Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have identified a mechanism that protects the female brain from genetic diseases. Although one of the two X chromosomes is ...

In a milestone achievement, a whole chromosome has been created from scratch by scientists for the first time ever. The tRNA Neochromosome is a man-made chromosome of the common baker's yeast ...

Yale scientists have discovered a new potential treatment avenue to fight cancer. Using CRISPR gene-editing, the team eliminated extra chromosomes from cancer cells and found that they could no longer ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

Triploidy is a condition that affects 1% to 3% of pregnancies. It’s when a developing baby has an extra set of chromosomes, the thread-like structures that carry DNA. A triploidy pregnancy usually ...

In most mammals, females have two X chromosomes and males have one X and one Y chromosome in each of their cells. To avoid a double dose of X-linked genes in females, one of the Xs is silenced early ...

“We’ve known that tiny fragments of ancient DNA can survive for long periods of time,” said Dr. Marcela Sandoval-Velasco of the Center for Evolutionary Hologenomics at the University of Copenhagen and ...
