Karn & Penrose showed that birth weight follows a normal distribution, that mortality for newborns is greater for those either under-or over-weight, and that the mean birth weight (7 lbs) coincides with that showing minimum mortality. The type of natural selection operating here is shown by the graph :
1. (a)
2. (b)
3. (c)
4. Both (a) and (b)
