Understanding Meiosis and Its Role in Sexual Reproduction

Meiosis

Cell division for sexual reproduction, producing gametes.

Diploid

Cells with two sets of chromosomes, 2n.

Haploid

Cells with one set of chromosomes, 1n.

Somatic Cells

Body cells, containing 46 chromosomes in humans.

Gametes

Sex cells, including sperm and egg.

Interphase

Phase before meiosis where DNA replication occurs.

Crossing Over

Exchange of genetic material between homologous chromosomes.

Chiasmata

Points where crossing over occurs during meiosis.

Nondisjunction

Failure of chromosomes to separate properly during meiosis.

Spermatogenesis

Process of sperm cell development in males.

Oogenesis

Process of egg cell development in females.

Meiosis Stages

Includes Prophase, Metaphase, Anaphase, Telophase, Cytokinesis.
