MeiosisOne diploid Cell creates 4 haploid cells.

Diploid Cell= pairs of similar chromosomes (Humans have 46 chromosomes in 23 pairs)

Haploid Cells= does not have pairs of chromosomes (Human has 23 different chromosomes)

Prophase IChromatid pairs are visible.

Duplicated chromosome pairs come near similar duplicated pairs.

Spindle Fiber forms

Nuclear memebrane breaks down.

Page 5: Meiosis

Metaphase IDuplicated chromosomes line up in the middle of the cell next to similar chromosome pair.

Spindle fiber connects centrioles to chromosome PAIRS.

Page 6: Meiosis

Anaphase I

Chromosome PAIRS move away from their similar chromosome pair.

Spindle fiber pulls the chromosome pairs towards the centrioles

Page 7: Meiosis

Telophase I

Cytoplasm divides

Two new cells are formed

No nuclear membrane is formed

Page 8: Meiosis

Meiosis II

Page 9: Meiosis

Prophase II

Chromosome pairs are visible in both cells.

Spindle Fiber forms.

Page 10: Meiosis

Metaphase II

Chromosome pairs line up in the middle of the cell.

Spindle fiber attaches to each chromosome.

Page 11: Meiosis

Anaphase II

Spindle Fiber separates chromosome pairs into single chromosome

Chromosomes are pulled towards the centrioles.

Page 12: Meiosis

Telophase IISpindle Fiber disappears

Nuclear membrane forms around chromosomes

Cytoplasm seperates

FOUR new cells are formed with two chromosomes each.

Page 13: Meiosis

Meiosis Ends

4 different haploid cells are made.
