    High School Lab
    In this chromosome modeling lab, students create pairs of socks models of chromosomes to model the processes of mitosis, meiosis, and fertilization. Students also build a foundation about meiosis and fertilization and how it relates to genetics and genetic disorders.

    High School Worksheet
    In this meiosis chromosome worksheet, students answer questions about the number of chromosomes generated by either mitosis or meiosis. Haploid and diploid chromosome numbers help students understand the reproduction type used in each process.

Meiosis Topics

  • Chromosome - histones, nucleosomes, chromatin, coils, supercoils, chromatid, centromere, homologous chromosomes, autosomes, XY and XX sex chromosomes.
  • Genetic Varaition - sexual reproduction vs. asexual reproducation, crossing over, law of segregation, mutation
  • Animal Chromosome Numbers - human = 46, gorilla - chimpanzee - orangutan = 48, dog = 78, housefly = 12, mosquito = 6.
  • Plant Chromosome Numbers - pea plant = 14, rye - 14, corn - 20, wheat bread - 42.
  • Meiosis - homologous chromosomes, gametes, polyploid, diploid, haploid, gonads, sperm, egg, zygote.
  • Karyotype - prenatal testing, amniocentesis, cvs, error in chromosome numbers, aneuploidy, monosomy.
