Individual A can derive fitness benefit of 160 units by helping Individual B, but incurs a fitness cost of 50 units in doing so following Hamilton’s rule, A should help […]

Based on the theory of kin selection, choose the correct statement: (1) A gene for altruism will spread in the population if the act of altruism increases the actor’s gene […]

The idea that an altruistic gene will be favored if r>C/B, where r is the coefficient of relatedness, B is the benefit to the recipient of the altriusm, and c […]

According to Hamilton’s rule, altruistic behaviour can evolve when rb>c, where b is the extra benefit gained by the recipient as a result of the altruistic act, c is the […]

According to Hamilton’s rule, ‘r’ is the coefficient of relatedness between two interacting individuals, ‘B’ is the benefit to the recipient and ‘C’ is the cost of the donor. Which […]

In an altruistic act, if a donor sacrifices ‘C’ offspring which helps the recipient to gain ‘B’ offspring and the donor is related to the recipient by a coefficient γ, […]

The correct expression of Hamilton rule for the evaluation of altruism is [C = the cost of a behavioral act to the actor, b = the benefit of that act […]

Natural selection is primarily based on fitness, which is dependent on maximum number of offspring laid for next generation. But at present new evolutionary concept is added in animal behaviour […]

An individual’s ability to pass down their genes—both through their offspring and the offspring of close relatives with shared genes. This is termed as (1) Inclusive fitness (2) Darwinian fitness […]

A researcher intends to stimulate neurons via glutamate receptors in medial septum of an experimental animal. The following apparatus/ instruments are available in the laboratory: A. Stereotaxic apparatus B. Slow […]
