Change of frequencies of alleles in a population or any deviation from Hardy-Weinberg equilibrium is interpreted as:

In the apparatus of the Urey and Miller experiment, the gases [G] contained in the flask are:
1. | Methane, Carbon dioxide, Ammonia, and Water vapour |
2. | Methane, Hydrogen cyanide, Ammonia, and Water vapour |

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)

2. | Dinosaurs, Therapsids, Thecodonts, and Pelycosaurs |
3. | Pelycosaurs, Therapsids, Thecodonts, and Dinosaurs |
4. | Theraosids, Dinosaurs, Pelycosaurs, and Thecodonts |
