Meiosis Project

Meiosis: is a process in which four daughter cells are created at the end with only half of the chromosomes as the parent cells.

Meiosis 1:

• Prophase 1-In prophase one of meiosis, pairs of homologous chromosomes intertwine and crossing over occurs as chromatids from homologous pairs of chromosomes exchange genetic information.
• Metaphase 1- The chromosomes line up in the middle of the cell, and fully formed spindle fibers attach themselves to the chromosomes.
• Anaphase 1- The spindle fibers then pull the homologous chromosomes, separating them to the opposite sides of the cell.
• Telophase 1- The parent cell then separates into two haploid daughter cells. 

Meiosis 2:

• Prophase 2- Each of the daughter cells have half the number of chromosomes as the parent cell. The difference between prophase 1 and prophase 2 is that the DNA is not replicated before.
• Metaphase 2- Kind of like metaphase one the chromosomes line up in the middle of the cell. 
• Anaphase 2- The sister chromatids separate and move to opposite ends of the cell also like metaphase one but there are half the number of chromosomes.
• Telophase 2- Meiosis 2 ends up with  4 haploid daughter cells with half the number of chromosomes. If it is a male then they will turn into four sperm cells. If it is a female then they will turn into eggs, but one will be bigger than the others.
