What can DNA fingerprints be used for?
Who is the murderer? Who's that baby's daddy? (paternity), and who is the close relative to that species?
Huntington's disease is a dominant genetic condition. If a man who is heterozygous for the gene and a woman who does not have Huntington's have a child, what are the chances that the child will have Huntington's?
What is 50%?
What is an example of a trait that is partly genetic and partly environmental?
cancer, height, obesity
List a 3 sources of genetic variation.

Random/independent assortment
Crossing over
Draw a Punnett square that shows the cross between a carrier for cystic fibrosis and a person without cystic fibrosis. What is the chance that their child will be a carrier?
What is 50%?
What is the genotype of a woman who is a carrier for hemophilia?

What is the difference between a point mutation and a frameshift mutation?
Point - only 1 base in the DNA is changed. Frameshift - a base is added or deleted, which changes all of the codons after the mutation.
Describe the process of using genetic engineering to make human insulin.
Take DNA with instructions for making human insulin and put it in the plasmid of a bacterial cell. Now the bacteria produce human insulin.
