Meiosis I Meiosis II Meiosis During meiosis, a parent cell divides into four sex cells each with half the number of chromosomes as the parent cells. Sex cells of males are called sperm cells and sex cells of females are called egg cells. Anaphase I The chromosome pairs split and pull apart to opposite ends of the cell. Anaphase II The centromeres split and the single chromosomes move apart to opposite ends of the cell. Metaphase II Chromosome pairs line up in the middle of the cell. Prophase II Double-stranded chromosomes and spindle fibers reappear in each new cell. Telophase II & Cytokinesis Four sex cells are produced, each with only one chromosome from each original pair. Punnett Square female parent male parent A Punnett Square shows all the possible allele (gene) combinations in the offspring of two organisms. RR Rr Rr rr Rr Rr R r R r Prophase I Before meiosis begins, chromosomes in the parent cell are copied. The nuclear membrane breaks apart and spindle fibers begin to form. Telophase I & Cytokinesis The cells split and each of the two new cells formed has half the number of chromosomes. Metaphase I The chromosome pairs line up in the middle of the cell and the spindle fibers attach to each chromosome at the centromere. www.newpathlearning.com © Copyright NewPath Learning.
