If the probability of a mother inheriting a disease allele from her parents is 1/2 and the probability that she passes it to her child is 1/4. The chance the child will inherit the allele is 3/4. Assume the males are homozygous normal.

Humans display a tremendous amount of variation. It has been postulated that ‘no 2 humans are identical [except twins].’ What are two (of the three) ways human genetic variation is increased? Be sure to explain exactly how variation is increased.

Explain why the Golden State Killer case is controversial. Propose a way IGG (investigative genetic genealogy) could/should be used by law enforcement. 

In humans, a major gene controls a characteristic of red blood cells called the ABO blood type.  Use the symbols IA, IB and i to write the possible genotypes of: A. A woman with Type A blood ________________ B. A man with Type AB blood ________________ C. A man with Type O blood ________________ D. What kind of antibodies (immune cell proteins) does a person with Type B blood have? E. A woman with type O blood has a child with type A blood. What are the possible blood types of the father?
