7.  During which phase of meiosis does independent assortment occur?

8.  What does it mean when two genes are not linked? (keep going, more on next page!)

9.  What is the difference between a monohybrid and dihybrid cross?

10.  What is a pedigree?

11.  What does autosomal mean?

12. How would a pedigree for an autosomal dominant trait differ from a pedigree for an autosomal recessive trait?

2.  Describe how two major features of the genetic code provide evidence for common ancestry of all living organisms.

3.  Name a conserved metabolic process that provides evidence for common ancestry of all living organisms.

4. Why can a bacteria in which the human insulin gene has been inserted produce insulin?

2.  What type of experimental evidence would identify linked genes?

3.  The probability that linked genes will segregate together is called the _____  ______

4.  How is map distance calculated?

5.  If the map distance between genes A and B is 30 is map units, and the map distance between genes C and D is 10 map units, between which pair of genes would you expect to find a greater recombination frequency?

6.  True or false: Sex linked chromosomes are non-homologous

7.  Why are females more likely to be carriers for sex-linked recessive traits than males?

8.  How would a pedigree for a sex-linked recessive trait be different from a pedigree for an autosomal recessive trait?

9.  If crossing over is occurring between genes, we would expect to see phenotypes that are ____________  ___________ the parent phenotypes.

10.  PAUSE the video at 6:39!!!  Do it!! Ok, thank you :) In the skill practice question at 6:39 in the video, what is the TOTAL number of offspring that are the result of cross over events? (Look for the offspring whose phenotypes are different from the parental phenotypes)

11.  Now that you know the TOTAL number of offspring that are the result of cross over events, divide that number by the number of crosses (5) to find the mean number of cross over events, which is…………
