GENETICS STUDY GUIDE (Test – B Day, Wed. 3/14; A Day, Thursday, 3/15)
1. Distinguish between monohybrid crosses and dihybrid crosses.
2. Review pedigrees
3. Define and give examples of codominance and incomplete dominance.
4. Explain the processes of self-pollination and cross-pollination. Know the
reproductive structures of the flower that are involved.
5.
Distinguish between allele and a gene. A locus is a gene’s position on a
chromosome.
6. Distinguish between phenotype and genotype.
7. Describe what crosses Mendel made in order to get individuals of the F1
generation and F2 generation. What is a pure strain (or pure breed)?
8. What is the difference between heterozygous (heterozygote) and homozygous or
(homozygote).
9.
List and carefully explain Mendel’s three principles of inheritance. (see slides)
10.
Why are test crosses used? Make sure you can solve a test cross problem.
11.
Under what circumstances can the Rh (+ or – blood types) lead to problems in
unborn children? How can this be prevented or treated?
12.
Be able to determine the genotypes of blood types. What are antigens?
Be able to sketch the RBC’s of individuals with type A, B, AB, & O blood. Go
to Nobelprize.org to practice blood typing.
13.
Why are characteristics such as hemophilia and colorblindness rare in females?
Explain.
14.
How can lethal alleles affect phenotypic ratios that a punnett square predicts?
15.
Understand the difference between multiple alleles, polygenic traits, gene-linked,
and sex-linked traits. Be able to solve a representative problem for each.
