Mi-two-sis |
Mei-one-sis |
Produces body cells(Somatic cells) |
Produces sex cells(Gametes) |
Daughter cells diploid(2N) |
Daughter cells haploid(N) |
Two daughter cells produced |
Four daughter cells produced |
In metaphase chromosomes line up singley |
In metaphase I chromosomes line up as homologous pairs(synapsis) The two double chromosomes are called a tetrad when they are lined up side-by-side. Crossing over occurs during the formation of the tetrad |
One nuclear division |
Two nuclear divisions |
Produces cells for growth and repair |
Produces cells for sexual reproduction |
Daughter cells have two sets of chromosomes(pairs) |
Daughter cells have only one member of each pair of chromosomes |
Daughter cells are genetically identical to the parent cell |
Daughter cells have one-half of the genes from the parent cell |
Insures that all daughter cells are genetically identical |
Generates genetic diversity through crossing over and ramdom seperation of homologous pairs of chromosomes |
