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 ...

A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female meiosis—the process by which germ cells are formed—in the model plant Arabidopsis ...

Chromosomes carry genetic information. Meiosis is a cell division process that produces germ cells - sperm and egg in animals, pollen and egg in plants - with half the usual chromosome number. During ...

Purpose: We evaluated whether the association of socioeconomic risk factors for trisomy 21 differed by type of maternal meiotic error. Methods: We determined meiotic ...
