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 ...

Cell division, the basic means by which genetic information is passed from generation to generation, involves tightly coordinated movements of a cell's DNA. This page describes the major phases of ...

Researchers have uncovered how successful chromosome segregation during sexual reproduction is achieved in plants. The ...

Sexual reproduction in eukaryotes depends on meiosis, which is a process that produces haploid gametes (e.g., egg and sperm cells in animals, ovules and pollen in flowering plants or spores in fungi) ...

If there was an award for the most creative way to gain extra credit in a science class, it would likely go to Julien Turner. A biology teacher at Morehouse College in Atlanta offered her students a ...

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 ...

How do we grow from a single fertilized egg into a fully grown person with trillions of cells? Our cells divide, of course! And it's no mean feat. Each time a cell divides, it must duplicate our 23 ...

The chromatids arrive at the either end of each cell and new nuclear membranes form. With meiosis in a female, there is only one dividing cell at this point. As in telophase I, the cytoplasm of the ...
