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 ...

Geneticists have been debating if meiosis requires only external or internal signals. Although earlier work revealed that an external cue from retinoic acid is needed, new research shows that ...

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 ...

Figure 1: Immunolocalization of meiotic proteins in wheat (W) and wheat–rye hybrids (WR) meiocytes in the presence (+) and absence (−) of the Ph1 locus. Meiocytes of wheat and wheat–rye hybrids were ...

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 ...

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 ...

Welcome to Mitosis vs. Meiosis. This half of the screen illustrates mitosis—the division of a cell's nucleus. Along with cytokinesis (the division of the rest of a cell), mitosis results in a parent ...
