Q

Sickle cell anemia gives what advantage? Common with what people ?

A

Heterozygous advantage for malaria. 1/12 african descent

17
Q

CCR5

A

Lack of CCR5 gene, so no CCR5 receptor protein made
- Stops HIV from being able to bind to surface of cell
Makes HIV immune
- very common and for european descent

18
Q

How is Lactose tolerance caused?
