meiosis
DESCRIPTION
TRANSCRIPT
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)
Meiosis I
Prophase I
Metaphase I
Anaphase I
Telophase I
Meiosis II
Prophase II
Metaphase II
Anaphase II
Telophase II
Prophase IChromatid pairs are visible.
Duplicated chromosome pairs come near similar duplicated pairs.
Spindle Fiber forms
Nuclear memebrane breaks down.
Metaphase IDuplicated chromosomes line up in the middle of the cell next to similar chromosome pair.
Spindle fiber connects centrioles to chromosome PAIRS.
Anaphase I
Chromosome PAIRS move away from their similar chromosome pair.
Spindle fiber pulls the chromosome pairs towards the centrioles
Telophase I
Cytoplasm divides
Two new cells are formed
No nuclear membrane is formed
Meiosis II
Prophase II
Chromosome pairs are visible in both cells.
Spindle Fiber forms.
Metaphase II
Chromosome pairs line up in the middle of the cell.
Spindle fiber attaches to each chromosome.
Anaphase II
Spindle Fiber separates chromosome pairs into single chromosome
Chromosomes are pulled towards the centrioles.
Telophase IISpindle Fiber disappears
Nuclear membrane forms around chromosomes
Cytoplasm seperates
FOUR new cells are formed with two chromosomes each.
Meiosis Ends
4 different haploid cells are made.
