WebNote: Metaphase II of meiosis can be differentiated from metaphase-I on the basis of the following features: (ii) Each chromosome of metaphase II has two chromatid (Fig. 7.3a) whereas in metaphase I these are paired homologous chromosomes each having two chromatids thus forming tetrad. (iii) In the metaphase I of meiosis, a few chiasmata are ... Webthe metaphase plate during Metaphase II. During Anaphase II, the sister chromatids separate and move to opposite poles. In Telophase II, the nuclear membrane reforms and cytokinesis occurs. Comparing Mitosis and Meiosis:--Mitosis occurs in somatic cells; meiosis occurs in germ cells.--Mitosis has one round of division; meiosis has two rounds.

MEIOSIS • The form of cell division by which gametes, with half the number of chromosomes, are produced. • Diploid WebMeiosis This is a special sequence of 2 cell divisions that produces haploid gametes from diploid germline cells. It starts with a diploid cell that has undergone chromosomal DNA replication: 2N chromosomes, 4X DNA content. Two successive divisions, with no additional DNA replication, results in 4 haploid gametes: 1N chromosomes, 1X DNA content.
