Multicellular eukaryotes and single-celled sex cells reproduce by a process called meiosis. In this process, the number of chromosomes in a mother cell is halved to produce gametes, cells that fuse ...

Meiosis is a specialized type of cell division in which two rounds of chromosome segregation follow a single round of DNA replication. In diploid organisms, meiosis generates gametes with a haploid ...

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 ...

With significant funding from the National Institutes of Health (NIH), a researcher at The University of Texas at Arlington is investigating fundamental biological processes that lead to fertility ...

A research collaboration based in Kumamoto University (Japan) has clarified how homologous chromosome pairing--a process necessary for sperm and egg formation where paternally- and maternally-derived ...

Investigators have employed mutant mice to study how the accumulation of genetic errors is managed during egg and sperm formation. Sometimes the best way to understand a biological process is to ...

Meiosis (pronounced /maɪˈoʊsɨs/ ( listen)) is a special type of cell division necessary for sexual reproduction. The cells produced by meiosis are gametes or ...

A new study led by Professor Kui Liu at the University of Gothenburg has identified the key molecule 'Greatwall kinase' which protects women's eggs against problems that can arise during the ...
