Understand what spermatogenesis is. Learn and discuss meiosis in spermatogenesis, seminiferous tubules, sperm cell precursors, and the anatomy of...
In plants, meristems are active areas of cell division (roots and shoot tips). In animals, cell division occurs throughout most tissues.There is a second kind of cell division, meiosis, which will be covered later. Meiosis is the kind of cell division that produces sperm, eggs and spores...
Meiosis is the two-step series of specialized cell divisions that makes sexual reproduction possible. Meiosis produces haploid cells, which contain just one member of every chromosome pair characteristic of an organism. In all animals, specialized cells in the reproductive organs, called germ cells, ...
In this lesson, learn about the process of meiosis, what is produced by the process of meiosis, genetic recombination in meiosis, and crossing over...
The primary follicles located in the ovary contain the only cells in the female that can complete the special form of cell division (meiosis) that produces gametes. In females the mature gametes are called egg cells or ova. The production of mature ova is not continuous. Each twenty-eight da...
The PAR on the short arms of the X and Y chromosomes (PAR1) undergoes pairing and recombination at meiosis. By contrast, the PARs on the long arms of the X and Y chromosomes (PAR2) pair only infrequently, and the homology observed in this region is probably maintained by gene conversion...

Meiosisproduces cells with half as many chromosomes as contained in body cells, called a haploid state, so that offspring have the correct number of chromosomes. In humans, body cells have a diploid, or doubled, number of 46, with 23 pairs of chromosomes. Each pair has a maternal and pate...
