He considered that the latter was as close to his estimate 0.141 for mutation rate
as could be expected in view of its utilization of only one bit of information. The
invalidation of the other method by the interaction eifect (not then apparent)

The lowest curve applies to such very extreme cases as that of a recessive lethal
with a mutation rate of 10- 4 per generation. The curve for v0s = 10- 6 applies to a
moderately detrimental type of mutation at a fairly typical mutation rate, ...
