Suppose there is a type of deleterious mutation in a particular human gene that causes death very late in life. Such mutations happen in about one in every million births, and can be passed on to descendants. Which statement about this allele is false? At equilibrium, the frequency of this allele will be zero. Selection against this mutation is weak compared to an allele that causes death at an earlier age. Medical advances that extend human lifespan will increase selection against this allele. Selection against this allele depends on the rate of extrinsic mortality.
