KNOW Chromosome Chromatid Centromere Mitosis Cytokinesis Asexual reproduction Sexual reproduction Gametes Zygote Fertilization Stem cells Diploid Haploid Homologous chromosomes Sex chromosomes autosomes Somatic cells Meiosis Genetic variation (or diversity) Crossing-over karotype UNDERSTAND Chromosomes form during cell division to insure the orderly division of DNA. Mitosis produces daughter cells that are genetically identical to the parent cell. Gametes (sex cells) are made during the process of meiosis and produce four daughter cells with half the chromosomes of the parent cell. Sexual reproduction is an advantage over asexual because it provides more genetic variation. DO Describe the structure & function of a chromosome. Place the stages of mitosis/cytokinesis in order and describe each. Describe how gametes and zygotes are related. Describe the process of meiosis and describe the type of cells it produces. Compare asexual and sexual reproduction. How individuals produced by asexual and sexual reproduction compare with their parents Compare the number of chromosomes in a gamete (sex cell) to the number in a somatic (body) cell. The difference between autosomes and sex chromosomes. Compare/contrast The differences between Meiosis and Mitosis. Determine a person’s gender and whether they have a genetic disorder from a karyotype.
