New research in an animal model of aging suggests a possible mechanism for why people with early menopause or other genetic conditions affecting the reproductive system are more likely to get ...

In the choreography of meiosis—the process responsible for sex cell division in all eukaryotic life—the pairing of homologous chromosomes (homologs) is essential. Errors in this process can lead to an ...

Researchers have uncovered how successful chromosome segregation during sexual reproduction is achieved in plants. The ...

1. The cytological work on record is briefly surveyed. There are reports on only nineteen species. Work has been confined to members of the tribe Cereeae, which is the most highly evolved tribe in the ...

As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced. Take the evolution of sex, for instance. To make the move from asexual to ...

Mating and meiosis -- the specialized cell division that reduces the number of chromosomes in a cell -- are related, but in most yeasts they are regulated separately. Not so in Candida lusitaniae, ...

The human body is made up of billions of cells. These cells grow and divide through a process called cell division. There are two types of cell division: mitosis and meiosis. Mitosis is a type of cell ...
