Mitosis produces 2 diploid cells (Essentially the end of Mitosis I) Meiosis produces 4 haploid cells (Meiosis II) Kinky People Can Often Find Good Sex Interphase the homologous chromosomes duplicate to form sister chromatids Prophase pairs of homologous chromosomes cross over; form tetrad Metaphase-indep assortment: can have diff variations the 23 pairs of homologous chromosomes line up in the center Anaphase the pairs of homologous chromosomes are pulled apart by spindle fibers Telophase the cell splits (cytokinesis) still contains entire chromosome (segregation) at the end of meiosis 1-2 dipload cells, then until the end of meosis II

Unformatted text preview: IPMATPMAT (I Punched MAT Punched MAT) Prophase II crossing over occurs again (when you share different genes on the chromosomes) AT THE END OF MEIOSIS TWO YOU CANNOT HAVE HOMOLOGOUS CHROMOSOMES BECAUSE YOU NEED VARIATION SO THEY SPLIT UP AND THEY ARE CALLED SISTER CHROMATIDS GAMETES: ONE SINGLE CHROMATID OF EACH CHROMOSOME; SOME GENTIC MAKEUP OF SOME OF BOTH PARENTS BECAUSE OF CROSSING OVER each gamete has 23 chromatids---when it meets a sperm which has 23 chromatids====the product will be 23 PAIRS of chromatids...
