1. What is the chromosome theory of inheritance?
2. Understand how independent assortment can cause gametes tohave four combinations of alleles when an individual isheterozygous for two genes on two different chromosomes.
3. What are linked characters and linked genes? Understand whylinked genes will not independently assort.
4. How can crossing over affect linked genes?
5. What are recombinant gametes?
6. Define recombinant frequency. Be able to use therecombinant frequency to determine how close two genes are on achromosome.
7. What is a linkage map?
8. What is the function of the SRY gene on the Y chromosome?What happens if you don't have this gene?
9. Know how sex is determined in mammals, birds, bees andants, and reptiles.
10. How many autosomes and sex chromosomes do normal humanhaploid and diploid cells have?
11. What does it mean for a gene to be X-linked orY-linked?
12. Be able to answer word problems and fill out a Punnetsquare involving an X-linked recessive trait.
13. Which sex is more likely to have an X-linked recessivedisorder? Understand why.
P.s The most simple answer would be preferable. I would becopping the notes over that you will provide to my noteb book andadd my details to it.
