Read just the long paragraph below and explain in your words the hypothesized evolutionary processes (note, more than one are in play) proposed to remove slightly deleterious alleles from the gene pool. Keep in mind the importance about balance between mutation rates and the consequences to individual fitness. "At first sight, it appears paradoxical that nearly neutral mutations in essential immune genes will be efficiently removed from the species’ gene pool despite having no easily discernible impact on the immune...
