Meiosis, Mitosis, and Cloning

Meiosis: A cell that produces 4 daughter nuclei and is only used for sexual reproduction that requires 2 nuclei divisions

Mitosis: A cell that produces 2 daughter nuclei and is only for asexual reproduction and growth that requires only 1 nuclei division

Cloning: Cloning requires only your cell and it copies it exactly

Differences between Meiosis, Mitosis, and Cloning:

Meiosis:

• Requires 2 nuclear divisions, 
• Chromosomes synapse and cross over, 
• Centromeres Survive one anaphase, 
• Halves chromosome number, 
• Producers 4 daughter nuclei, 
• Produces daughter cells genetically different from parent and each other, 
• Used only for sexual reproduction 

Mitosis:

• Requires 1 nuclear division, 
• Chromosomes do not synapse nor cross over, 
• Centromeres dissolve in mitotic anaphase, 
• Preservers chromosome number, 
• Produces 2 daughter nuclei, 
• Produces daughter cells genetically identical from parent and each other,
• Used for asexual reproduction and growth 

Cloning:

• so far we can't clone humans yet, but we have cloned a sheep
• use small pipets to grab the cell and extract the nuclei from the cell and transfer it to another cell
