Cell Division and Genetics
Cell Structure and function, Cell Division, Mendelian
Genetics, Human Inheritance and Genetic Disorders
By the end of this Unit, you will be able to answer the following questions:
1. Describe the functions performed by organelles in the cell.
2. Compare and contrast bacterial, animal, and plant cells.
3. List the events that take place during the three stages of the cell cycle.
4. Identify and describe the events that occur during both mitosis and meiosis.
5. Describe the role of chromosomes in inheritance.
6. Describe Mendel’s genetics experiments and explain how geneticists use symbols to represent alleles.
7. Describe the principles of probability and how Mendel applied them to inheritance.
8. Use Punnett squares to predict the probability of traits in offspring.
9. Explain the concepts of multiple alleles, multiple genes, and sex-linked traits.
10. Describe how geneticists use pedigrees.
11. Describe the causes and symptoms of some major human genetic disorders.
