  1. Geographical isolation

  2. Mechanical isolation

  3. Temporal isolation

  4. Hybrid sterility

  5. Behavioral isolation

Show answer
Correct Option: B
Explanation:

The presence of populations of a species in distant localities preventing the gene flow between them leads to geographical isolation. Different periods of attainment of sexual maturity leads to temporal isolation. Abnormal distribution to the gametes of whole chromosomes, chromosome segments, or combinations of genes leading to infertile hybrid is one of the post-zygotic isolation. Incompatible premating behavior leading to no attraction between groups for mating is termed as behavioral isolation. Incompatible differences in reproductive structures leading to prevention of cross-fertilization refer to as mechanical isolation. 

Therefore, the correct answer is option B.

  4. Altruism results in other individuals performing altruistic acts in return.

  5. Altruism increases the number of young of genetically similar individuals.

Show answer
Correct Option: E
