Question 1

From analysis of mitochondrial DNA mutations, it has been proposed that all humans have descended from a population in:


◦ South America.
◦ Europe.
◦ North America.
◦ Asia.
◦ Africa.

Question 2

In a genetic cross between two flies, one with dark eye pigment and a single DNA fragment hybridizing with a probe and one lacking pigment and having two fragments hybridizing with the probe, results in progeny with 40% of one parental type and 40% of the other parental type, and 10% of each of the recombinant phenotypes. What is the genetic map distance between the restriction marker and the eye color marker?


◦ 10%
◦ 20%
◦ 40%
◦ 50%
◦ 80%
