Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are ...

Scientists have long known that maturing egg cells, called oocytes, generate internal, twister-like fluid flows to transport nutrients, but how those flows arise in the first place has been a mystery.

"When yeast cells kiss": two haploid yeast cells of different mating types approach each other for mating. Use of images is limited to editorial coverage of scientific topics relating to the ...

Thus, the products of meiosis II are four haploid cells that contain a single copy ... are already much larger than sperm, and the future egg retains most of this volume as it passes through ...

During sexual reproduction, haploid gametes (i.e. eggs and sperm) are generated from diploid precursors through the specialized cell division of meiosis. Meiosis reduces ploidy by following one round ...

If you're male, your body uses meiosis to create sperm cells; if you're female, it uses meiosis to create egg cells. Others cells in your body contain 46 chromosomes: 23 from your father and 23 ...

In an advance for treating male infertility, researchers transplanted a patient with his own sperm-forming stem cells that ...

The nucleus of a germline stem cell undergoes two divisions, firstly separating homologous chromosomes and secondly separating chromatids. Haploid gametes contain 23 single chromosomes.

Now MIT scientists have used light to control how a single cell jiggles and moves during its earliest stage of development. The team studied the motion of egg cells produced by starfish—an ...

If you're male, your body uses meiosis to create sperm cells; if you're female, it uses meiosis to create egg cells. Others cells in your body contain 46 chromosomes: 23 from your father and 23 ...
