    Study Notes

    Meiosis

    • Meiosis is a division process that occurs in the gonads and results in four daughter cells, each with half the number of chromosomes as the parent cell.

    Chromosome Reduction

    • In humans, meiosis reduces the number of chromosomes from 46 to 23.

    Inheritance

    • Each person inherits 23 chromosomes from each parent: one set from an egg and one set from a sperm.

    Cell Division

    • Meiosis occurs in gonads, not in somatic cells.

    Chromosome Structure

    • A chromosome consists of chromatin (DNA + protein).
    • Chromatids are connected at the centromere.
    • Sister chromatids are identical copies of DNA.
    • Homologous chromosomes are chromosomes that pair up during meiosis.
    • Chromosomes have centromeres that hold sister chromatids together.
