Transcript of Meiosis

Meiosis
Important Things To Remember
Sexual Reproduction involves two parents
Offspring receive half DNA from mom and half DNA from dad
Chromosomes
A human body cell contains 46 chromosomes.
23 from mom and 23 from dad
Chromosomes
The pair of chromosomes that contain the same traits are called homologous chromosomes.
One is from mom and one is from dad.

Types of Cells
A sexually reproducing organism has 2 types of cells - body cells and sex cells.
Body cells contain pairs of chromosomes and are called diploid cells.
Sex cells contain one copy of the chromosome and are called haploid cells.
Prophase I
Chromosomes condense
Homologous chromosomes pair up
Nuclear membrane breaks apart
Metaphase I
Homologous chromosomes line up in the center of the cell.
Spindle fibers attach to each chromosome.
Anaphase I
Homologous chromosomes seperate and are pulled apart to opposite ends of the cell.
This is done randomly.
Telophase I
Cytoplasm divides
Nuclear membrane forms around two daughter cells
Prophase II
Nuclear membrane breaks apart
Metaphase II
Chromosomes line up in the middle of the cell
Spindle fibers form
Anaphase II
Chromosomes are pulled apart into sister chromatids
Sister chromatids move to opposite ends of cell
Telophase II
Nuclear membrane forms around each set of sister chromatids
Four haploid cells form
