When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...

During cell division, chromosomes are duplicated and separated so that one copy of each chromosome is inherited by each of the two emerging daughter cells. Correct distribution of chromosomes requires ...

This is a preview. Log in through your library . Abstract Previous efforts have shown that mutations in the Drosophila zw10 gene cause massive chromosome missegregation during mitotic divisions in ...

Scientists have discovered an amazingly simple way that cells stabilize their machinery for forcing apart chromosomes. Their findings are reported Nov. 25 in Nature. When a cell gets ready to split ...

Abnormal chromosomes can present challenges during cell division. A new study shines light on how this dysfunctional process may produce mutational patterns commonly found in cancer cells. Every time ...

As close as we’ve gotten to sequencing the entire human genome, there are still a few gaps. But now geneticists have plugged a major one in a landmark new study, by sequencing the entire human X ...

During sexual reproduction, haploid gametes (i.e. eggs and sperm) are generated from diploid precursors through the specialized cell division of meiosis. Meiosis reduces ploidy by following one round ...

A new study from UC Davis shows that the pesticide atrazine in drinking water accelerates aging in mouse egg cells and chromosomes. (Getty Images) Female infants are born with several million immature ...
