My Notes
Industrial melanism is an example of
1. defensive adaptation of skin against ultraviolet radiations
2. drug resistance
3. directional selection due to smoke from industries
4. protective resemblance with the surroundings
If a new allele suddenly becomes very abundant in a population, most likely it is:
1. mutating rapidly
2. flowing with emigrants
3. strongly selected for
4. a product of assortative mating
Which of the following conclusions is from industrial melanism?
(1) Camouflage causes the white moths to get caught by predators more even in rural areas during industrialisation.
(2) During industrialisation, white variant of moths got wiped out completely in urban areas.
(3) During industrialisation, lichen will increase in number.
(4) In a mixed population, those that can better adapt, survive and increase in population size.
Which one of the following is not a living fossil?
1. King crab
2. Sphenodon
3. Archaeopteryx
4. Peripatus
