1 Meiosis Review

2 Meiosis I: Replication

3 Interphase I DNA Replication DNA Replication Chromatin a ball of yarn Chromatin a ball of yarn

4 Prophase I Chromosomes coil and condense Chromosomes coil and condense Form a tetrad (synapsis) Form a tetrad (synapsis)

5 Metaphase I Tetrads align along equator Tetrads align along equator

6 Anaphase I Tetrads split Tetrads split Form dyads Form dyads Dyads move to opposite poles Dyads move to opposite poles

7 Telophase I Cleavage furrow forms Cleavage furrow forms Cell splits (cytokinesis) Cell splits (cytokinesis) Form two diploid daughter cells Form two diploid daughter cells

8 Meiosis II: Reduction Division

9 Interkinesis Similar to Interphase I Similar to Interphase I No DNA replication No DNA replication

10 Prophase II Chromosomes condense and coil Chromosomes condense and coil

11 Metaphase II Chromosomes align along equator Chromosomes align along equator

12 Anaphase II Dyads split at centromere Dyads split at centromere Chromatids move to opposite poles Chromatids move to opposite poles

13 Telophase II Cleavage Cleavage furrow forms furrow forms Cell splits Cell splits Both diploid Both diploid cell splits cell splits Forms 4 haploid daughter cells Forms 4 haploid daughter cells
