They are also referred to as sex cells. 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 ...

A sperm cell and an egg cell each contain half the DNA to make a person. Encoded in that DNA are genes – instructions on how to make everything from eyelids to elbows. Some traits, like height ...

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 ...

While using a light microscope to study sperm formation in wasps, Henking noticed that some wasp sperm cells had 12 chromosomes ... a light microscope to study egg formation in female grasshoppers ...

Germ cells and sex cord stromal cells form when a fetus (baby) is developing. A fetus is made from a sperm cell and an egg cell. Germ cell tumors (GCTs) are also known as germ cell cancer. Germ cells ...

A team of researchers from Monash University has uncovered how swimming sperm create corkscrew-shaped fluid vortices that help propel them forward, improving their chances of reaching the egg. The ...

Women who decide to have children in middle age depend on sperm and egg resiliency. Part of germ cell (also known as egg cells and sperm cells) resilience depends on a functional piRNA pathway to ...
