Question 1

Describe how genes on the same chromosome will segregate.

Answer 1

segregate together during meiosis unless separated by crossing over

Question 2

Explain the relationship between frequency of recombinant progeny and map distance.

Answer 2

As the physical distance between genes increases, the probability of recombination increases

Question 3

Calculate map distances from the frequency of recombinants in testcrosses.

Answer 3

(recombinant progeny)/(total progeny)*100=map distance

Question 4

Explain how human genetic maps are generated

Answer 4

• In human genetic mapping we use things like SNPs (genetic markers) to analyze pedigree trees
• Using the recombination frequency you are able to find out how far apart they are in centimorgans
