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 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 ...

Mitosis and meiosis are both processes by which cells reproduce, but there are distinct differences between the two. While new cells are generated during mitosis, meiosis is a special type of cell ...

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 ...

Meiosis produces sperm and eggs with exactly half the chromosome number of the individual producing the gametes. To ensure that each gamete has one copy of each chromosome pair, the diploid cell ...

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 ...

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, ...

More than one-sixth of adults around the world experience infertility in their lifetime. There is a high unmet need not only for increased access to affordable, high-quality fertility care for those ...

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 ...
