Mysteries of reproduction A gene that controls whether germ cells eventually become sperm or eggs has been identified by scientists. Their research, which provides insight into the mysterious biology ...

Older mice have more new mutations -- changes in DNA sequence that occur in the individual rather than being inherited from a parent -- than younger mice in the genomes of their mitochondria, ...

It’s not just about chromosomes. Or reproductive cells. Or any other binary metric. Many genetic, environmental and developmental variations can produce what are thought of as masculine and feminine ...
