G9 ch 10 meiosis
Meiosis is the process by which diploid cells in organisms undergo two cell divisions to produce haploid gametes, such as sperm or egg cells, with half the number of chromosomes. The document defines key terms related to meiosis such as homologous chromosomes, haploid, diploid, and crossing over. It also provides a table showing the number of chromosomes in diploid cells and gametes of various organisms, including humans having 46 chromosomes in diploid cells and 23 in gametes.
