Evolution in Action Flashcards
1
Q
Give an example of how humans are still evolving:
A
Vivax Malaria resistance
2
Q
How does the Vivax enter the RBC?
A
Using the duffy gene
3
Q
Why is it advantageous to be a homozygous duffy mutant?
A
You do not synthesise the duffy protein therefore the Vivax cannot enter the RBC so you have resistance to Vivax malaria
4
Q
Why can the resistance not be explained by genetic drift?
A
The percentage resistance is too high
5
Q
Why will selection still be occuring?
A
There is no acess to anti-malarial drugs in Madagascar
