Tetrads (two homologous chromosomes X two chromatids each) line up on metaphase     plane

Each daughter cell receives one member of each homologous pairEnd result of Meiosis I:  Two haploid cells containing 2 chromatids of each chromosome.

• Prophase/prometaphase  -- chromosomes form, nuclear envelope
• disintegrates, etc.Metaphase – Individual chromosomes line up on       
•      metaphase plate

• Anaphase – Sister chromatids separateTelophase – Cytokinesis to yield
• gametes with        one member of each homologous pair        one copy
• (chromatid) of each chromosome
