SBI 3U GENETIC CONTINUITY

CHAPTER 4 AND 5 REVIEW

You should be able to:

  1. Recognized the DNA replication for cell division occurs during interphase.
  2. Demonstrate an understanding of the process and importance of mitosis (e.g. cell division, and the phases of mitosis)
  3. Draw and label diagrams of the four stages of mitosis.
  4. Explain the terms: diploid, haploid, 2n and n number of chromosomes, homologous chromosomes, synapsis and tetrad.
  5. State the main purpose of the process of meiosis.
  6. Explain the process of meiosis in terms of the replication and movement of chromosomes.
  7. Draw and label diagrams of the many stages of meiosis.
  8. Explain the number of chromosomes in cells before, during, and after mitosis and meiosis.
  9. Compare the processes of mitosis and meiosis.
  10. Describe the procedure and state the results of Mendel’s monohybrid crosses that allowed him to deduce how characteristics are inherited and formulate his first law of heredity: the law of segregation
  11. Define or explain the following terms: gene, allele, homozygous, heterozygous, hybrid, dominant, recessive, genotype and phenotype.
  12. Explain, using Mendellian genetics the concepts of dominance, co-dominance, incomplete dominance and recessiveness.
  13. Give appropriate lettered symbols to represent alleles and genotypes.
  14. Describe the phenotype given a genotype. Determine the genotype(s) given a phenotype.
  15. Determine the kinds of sex cells that a individual can produce.
  16. Predict the outcome of various genetic crosses.
  17. Solve problems involving monohybrid crosses using a Punnett square.
  18. Describe the procedure and state the results of Mendel’s dihybrid crosses that allowed him to deduce how characteristics are inherited and formulate his second law of heredity: the law of independent assortment.
  19. Determine the kinds of sex cells dihybrid individuals can produce.
  20. Solve problems involving dihybrid crosses using a Punnett square.
  21. State the characteristics and solve problems for incomplete dominance or codominance.
