Genetics
1.
Define heredity, inheritance and genetics.
2.
Define probability. How is it calculated? What are the various ways that it can be
written?
3.
Make sure that you can determine the probability of a single event occurring and the
probability of independent events occurring simultaneously (Think of the lab with the die
and coins).
4.
Who is Gregor Mendel?
5.
What organism did Mendel study and what were the advantages of using that organism?
6.
What does it mean if a flower is described as monoecious?
7.
Describe the difference between self- and cross-pollination?
8.
What does it mean if an organism is said to be true breeding?
9.
What is the difference between the diploid and the haploid number of chromosomes?
Gametes have the ______________ number of chromosomes.
10. Differentiate between a gene, a trait and an allele.
11. Give an example of a trait and a possible allele for that trait.
12. Describe Mendel’s experiments (what was crossed and what were the results) using the
following terms: parental generation (P), first filial generation (F1) and second filial
generation (F2)?
13. List and describe each of Mendel’s 3 principles.
a.
b.
c.
14. Define and/or provide examples for the following terms:
a. Genotypeb. Phenotypec. Homozygousd. Homozygous dominante. Homozygous recessivef. Heterozygous15. Make sure that you can solve problems involving monohybrid and dihybrid crosses (refer
to your practice problems).
16. What scientist studied genetics after Mendel through experimentation with fruit flies?
17. What is an advantage of using fruit flies?
18. Give examples and explain the following patterns of inheritance:
a. Incomplete dominanceb. Codominancec. Multiple allelesd. Polygenic traits19. Give an example(s) of the effect of environmental conditions on the expression of genes?
