I'm adding this without reading ALL of the posts but if I'm not correct, Sicle Cell Anemia IS in fact a beneficial mutation. People that have that mutation are far less likely to die from Malaria.<hr size="1" /></blockquote><span class='postcolor'>
Actually, having a single allele is a beneficial mutation. Unfortunately for those who get both alleles, it is not beneficial at all, rather the painful, deadly disease. But you are right that the disease exists because of the mutation that confers beneficial immunity on the larger number who will inherit the single allele. |
