Why does sickle cell anaemia tend to be most common in areas where malaria is also present?
Having malaria makes you immune to sickle cell anaemia.
The mosquitoes that transmit malaria also carry sickle cell anaemia.
The pathogen that causes malaria causes mutation of the sickle cell allele.
People who have one copy of the sickle cell allele are less likely to die from malaria.

Difficult Round:
The gene for blood clotting factor VIII is found on the X chromosome. There are two alleles of this gene, the dominant H producing normal factor VIII and the recessive h resulting in a lack of factor VIII.

0%
25%
50%
100%
