Overall, the average heritability of all expression traits was 0.0005; considering only the 3385 traits with nonzero estimates of among-line variance in model (1) (i.e., the traits for which there is some evidence that a mutation might have occurred), the average mutational heritability was 0.0018.

While it seems counterintuitive that a mutation that is so common would be related to preventing the reproduction of a species, Dr. Bevins said the mutation might have survived because it has another function, still unknown but useful.

There is a caveat to this reasoning, however, because there is also the possibility that the new mutation might have occurred in a progenitor germ cell in one of the parents, so that some unknown proportion of that individual's eggs or sperm may carry the mutation, even though it is absent from the somatic cells including blood, which is generally the tissue sampled for testing.
