Meiosis
Meiosis : produces sex cells by reducing their chromosome number by half
Important because it creates genetic variation
Meiosis 1- sexual nuclear division - 4 haploid gametes
Prophase l - nuclear envelope breaks, Centuro some separate,
spindle fibre for crossing over between homologous.
Metaphase l - Homologs line up at metaphase plate.
Spindle fibre attached to kinetochores
Anaphase l - Homologous pulled apart but sister
chromatids are still attached.
Telophase l - nuclear envelope reform around sister
Sister chromatid . Cytokinesis happens at the same time.
Meiosis l product : 2 haploid daughter cells with duplicate DNA
( Double mothers OR father DNA)
