Meiosis
MEIOSIS 1
Interphase:
• Chromosomes replicate
• Chromatin condenses
Prophase 1:
• Pairing of omogous chromosomes occurs each chromosome concicts of two
chromatids
• The neuclear envolpe breaks down
• Spindles form
Metaphase 1:
• Homologous chromosomes line up at the equater
• Chromosome centromers attach to spindle fibers.
Anaphase 1:
• Homologous chromosomes separate and move to opposite poles of the cell.
Telophase 1:
• The spindles break down chromosomes uncoil and form two nuclei,
• The cell divides.
MEIOSIS 11
Prophase 11:
• Chrommosomes condense.
• Spindles from in each new cell.
• Spindle fibers attach to chromosomes
Metaphase 11;
• Centromeres of chromosomes line up
randomly at the equator of each cell.
Anaphase 11:
• Centomeres split
• Sister chromatids seprate and move to
opposite poles
Telephase 11:
• Four nuclie from around chromosomes
• Spindles break down
• Cells divide
