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 ...

The recombination between parental chromosomes, a characteristic of sexual reproduction, plays a crucial role in evolution.

In evolutionary terms, fitness is defined as an organism's ability to survive and reproduce its genes into the next ...

A study led by bioengineers at the University of California San Diego sheds new light on how a type of heart valve disease, called aortic valve stenosis, progresses differently in males and females.

Since ancient times, scientists and philosophers have pondered the fundamental question of what makes some organisms male and some female. Some hypotheses were at least plausible—Greek philosopher ...
