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 ...
A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female ...
Sometimes the best way to understand a biological process is to disrupt the normal process and analyze the result. That’s why Sloan Kettering Institute (SKI) researchers used a strain of mutant mice ...
In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...
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 ...
In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for ...
During meiosis, paternal and maternal chromosomes duplicate, pair, and exchange parts of their DNA in a process called meiotic recombination. In order to mediate this exchange of genetic material, ...
The process of meiosis involves genetic shuffling that dilutes the desirable traits of sexually reproducing crops. Identification of a mutation in which shuffling does not occur is a step forward for ...
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 ...

There is a high unmet need for accessible, affordable, and high-quality fertility care, as approximately 1 in 6 people are affected by infertility worldwide. While meiotic failure is a major cause of ...
