Meiosis:
- production of gametes: sex cells (have half as many chromosomes as other cells)
- separates sister chromatids + homologous chromosomes
- homologous pairs are separated during meiosis I
- sister chromatids are separated during meiosis II
Before meiosis I, the cell goes through interphase: grows during G1, copies chromosomes during S phase, prepares for division during G2.
Meiosis 1:
Reduction division (diploid to haploid) in which homologous chromosomes are separated.
Prophase 1:
- chromosomes condense/supercoil and pair up with their homologous partner
- homologous partners exchange part of their DNA thanks to the process of crossing over
Metaphase 1:
- homologous chromosomes line…
