GENETICS REVIEW SHEET
Chapters in textbook: Ch.6 and 7
You need to practice genetic problems!!!!!!!!
1. Who is considered the father of genetics? What did he study? What reasons did he study the plant he did?
2. Where are genes located? What are alleles?
3. What is Meiosis? Explain how it creates great genetic diversity. What is the advantage to genetic diversity among a
population?
3. Be able to identify the following patterns of inheritance and predict genotypic and phenotypic frequencies for:
dominant and recessive traits, incomplete dominance, and co-dominance.
4. What do the terms homozygous and heterozygous mean? Be able to give examples. Do the same for the terms
dihybrid and monohybrid.
5. Be able to make punnett squares and predict frequencies (genotypic and phenotypic) for various crosses including
dihybrid crosses.
6. What are the three principles Mendel derived? Be able to recognize examples of each principle.
7. Be able to determine from a pedigree, whether a trait is sex-linked, dominant, or recessive.
8. What are sex-linked traits? Why are males most affected? Who does a son inherit a sex-linked trait from - mother or
father? What is a carrier? Give two examples of human sex linked traits (ch. 7.4) Be able to follow inheritance and
predict genotypic and phenotypic frequencies.
9. What is a multiple - allele gene? Be able to apply a pedigree to blood typing problems to determine genotypes.
10. What is the difference between multiple allele and polygenetic traits? Give examples of each.
