Q

what happens in meiosis

A

Meiosis there is one chromosome
duplication followed by two cellular
divisions (into four cells) so Meiosis is
broken down into Meiosis I and Meiosis II.

Q

Compare Meiosis 1 and Mitosis

A

Meiosis I:
â–  Prophase I - pairing of
homologous
chromosomes
■ Metaphase I –
homologous pairs line up
at metaphase plate
■ Anaphase I – homologous
chromosomes separate
■ Telophase I – daughter
cells are haploid

â–  Mitosis:
â–  Prophase has no such
pairing

■ Metaphase –
chromosomes align at
metaphase plate
■ Anaphase – sister
chromatids separate

■ Telophase – diploid cells
