Re: Race specific Bomb... [censored] an Afro-gene?????
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: R_C</div><div class="ubbcode-body">The sickle cell gene is not "exclusive to black people". </div></div>
That's why I <span style="font-size: 14pt"><span style="font-weight: bold">asked</span></span> the question, because I don't know.
But this biologist has this to say:
<span style="font-style: italic">Most of the people vulnerable to this disorder are of African descent. Actually, if you overlap a map of the incidence of sickle cell disease with a map of the incidence of malaria, there is a strong correlation. The reason is genetics.
If you have the disease, untreated, you would die young and the disease should extinguish itself after enough generations. The reason why it persists is because being a carrier of the gene gives you resistance to malaria. You survive both diseases to pass on the sickle cell gene. If you mate with another carrier (neither of you have the sickle cell disease) your offspring could get the s.c gene from you and your mate, in which case, that child would have the disease.
So the gene persists in a population because it imparts some benefit...resistance to malaria.
It is very kind of you to be sensitive about the racial issue here. Be assured that this is not the only case of a population with a different gene pool. Type 2 diabetes is much higher among Scandinavians, and it is not related to lifestyle...it is all genetics. So black people are not alone in suffering from their genetic background. We are all a result of our past, to one degree or another.
