1. What is genetics?
2. Who was Gregor Mendel? Describe his experiments.
3. Describe the following laws/principles:
a. Principle of Dominance
b. Law of Segregation
c. Principle of Unit Characters
d. Law of Independent Assortment
4. How did Mendel name his generations?
5. Describe Walter Sutton’s Chromosome Theory of Heredity.
6. What is an allele?
7. What is the difference between a genotype and a phenotype?
8. What is the difference between homozygous and heterozygous? What are the
two types of homozygous genotypes?
9. What is a test cross?
10. Know how to complete monohybrid and dihybrid crosses!
11. What is the Product Law of Probability? Give an example.
12. What will the phenotype of a heterozygous organism be for an incomplete
dominant trait?
13. What will the phenotype of a heterozygous organism be for a codominant
trait?
14. What does it mean if a trait has multiple alleles?
15. What are the chances of a woman with Type AB blood and a man with type B
blood having an offspring with Type O blood? Explain.
16. What did Thomas Hunt Morgan use for his experiments?
17. Give the male and female genotypes for the sex chromosomes in humans.
18. What is an autosome?
19. If a male with normal blood clotting and a woman who is a carrier for
hemophilia have a child, what are the chances that they will have a son with
hemophilia? (Hemophilia is sex-linked recessive.)
20. What is polygenic inheritance?
21. Give an example of a human trait that shows continuous variation.
22. What are modifier genes? What human trait is a good example of a trait with
modifier genes?
23. How does an individual’s environment influence their phenotype? Give an
example.
