Meiosis By Trevor Corsello

Meiosis 1: One Dipoloid nucleus to Two Haploid Nuclei

Prophase 1

Homologous chromosomes condense, pair up, and swap segments.

Spindle microtubules attach to the chromosomes

Nuclear envelope breaks up

Metaphase 1

Homologous Chromosomes align midway between spindle poles.

Swindle microtubules attach 2 chromosomes to each side

Anaphase 1

Chromosomes separate and move toward opposite spindle poles

Telophase 1

Complete set of chromosomes at spindle poles.

New nuclear envelopes form

2 Haploid Nuclei form

Meiosis II: 2 Haploid Nuclei to 4 Haploid Nuclei

Prophase 2

Chromosomes condense

Spindle forms and attaches chromosomes to swindle poles

Nuclear envelope breaks up

Metaphase 2

Chromosomes align midway between spindle poles

Anaphase 2

Sister chromosomes move toward opposite swindle poles

Telophase 2

Chromosome clusters arrive at swindle poles

New Nuclear Envelopes form

Chromosomes loosen up
