<span>This would be an example of a mutation, because the changing of allele frequencies would be a change within the gene itself, which would be a mutation in the DNA. This is evidenced by the fact that there is now a form of human resistance to malaria, due to changes within human DNA itself.</span>
Like transpiration in plants mammal's hypothalamus makes sweat glands functional and mammal's body secretes sweat which on evaporation decreases the body temperature
If the disease was cause by the dominant allele, every person with said gene would be affected with the disease. if the genetic allele is recessive, both parents can be carriers (hetero) without being affected. that makes it easier for the genes to keep being passed on.
hope this helps!
America, Russia or China.
Probably America though.
