meiosis

Type: Term Pronunciation: mī-ō′sis Definitions: 1. A special process of cell division comprising two nuclear divisions in rapid succession that result in four gametocytes, each containing half the number of chromosomes found in somatic cells. Synonyms: meiotic division

meiosis

A two-stage type of cell division in sexually reproducing organisms. In meiosis, a diploid cell divides to produce four haploid cells, each with half the original chromosome content. For this reason, meiosis is often called a 'reduction division'. In organisms with a diploid life cycles, the products of meiosis are usually called gametes. In organi

Meiosis

The reduction division process by which haploid gametes and spores are formed, consisting of a single duplication of the genetic material followed by two mitotic divisions.

meiosis

The process in which a eukaryotic nucleus divides into nuclei whose ploidy is lower than that of the parent nucleus (typically, haploid nuclei being formed from diploid nuclei) and in which recombination usually occurs.

Meiosis

The process of division of sexual cells in which the number of chromosomes in each nucleus is reduced to half the normal number found in normal somatic cells. When two sexual cells fuse, each contributes its half of the chromosomes. The resulting embryo contains the full chromosome complement. Cells with half the chromosomes are called haploids,

Meiosis

Meiosis: The process of germ cell formation. During meiosis, each chromosome pairs with the other chromosome in the pair and they exchange segments of genetic material. In both women and men, the autosomes (non-sex chromosomes) pair. In women, the X chromosomes pair; and in men, the X and Y chromosome pair. After the exchange of genetic material, t

meiosis

A specialized form of nuclear division in which there are two successive nuclear divisions (meiosis I and II) without any chromosome replication between them. Each division can be divided into 4 phases similar to those of mitosis (pro-, meta-, ana- and telophase). Meiosis reduces the starting number of 4n chromosomes in the parent cell to n in each

meiosis

(mi-o´sis) the process of cell division by which reproductive cells (gametes) are formed. There are two successive divisions, meiosis I and meiosis II, in which four daughter cells are formed, each with the haploid number of chromosomes (23 in humans). As in mitosis, meiosis I and II are each divided into four phases: p...
