meiosis  There are two types of cell division: mitosis and meiosis Learn more about what happens to cells during each of these processes  The duplicated chromosomes align on a second spindle, and the sister chromatids separate to produce cells with a haploid DNA content Meiosis thus consists of a

Meiosis I and Meiosis II: Meiosis I produces two haploid cells from a diploid cell Meiosis II produces two haploid cells from each haploid Meiosis occurs in ovaries and testes, where a single cell divides twice to produce four cells containing half the original amount of genetic information

In humans, special cells called germ cells undergo meiosis and ultimately give rise to sperm or eggs Germ cells contain a complete set of 46 Lesson Summary Meiosis is a process in which a gamete-producing cell undergoes two cell divisions, known as meiosis I and meiosis II, to produce four gametes,
