In a population, homozygous & heterozygous individuals are in a certain proportion. This proportion can't be changed by

1. Natural Selection

2. Mutation

3. Recombination

4. Use and Disuse of organs

Biologists discover about 1000 species in an Island
which is descended from a single ancestor species.
What is the reason behind the such large speciation?
1. Mutation
2. Adaptive radiation
3. Convergent evolution.
4. Reproductive isolation

The sugar glider and flying squirrel belong to two different groups of mammals, but they have both evolved bushy tails and flaps of skin that help them exploit their forest environments more efficiently. This pattern of evolution is an example of :

1. Character displacement

2. Adaptive radiation

3. Convergent evolution

4. Divergent evolution

Natural selection is the survival of fittest, which of the
following most precisely describe the survival of fittest?

2. How many fertile offspring is produced by an
organism.
3. Capability to tolerate environmental extremities.
4. How long they survive.

Which of the following will not show convergent evolution?

2. Flippers of Penguins and Dolphins
3. Sweet potato and potato
4. Hearts of frog and rabbit

Which of the following factor will not affect Hardy-Weinberg equilibrium?
(1) Natural selection
(2) Genetic drift
(3) Genetic recombination
(4) Random mating
