Summary Introduction

Introduction:

Altruism is the selfless behavior shown by an individual that encourages it to help others. As per Hamilton’s rule, an altruistic gene can spread in a population only when the product of fitness benefit $\left(B\right)$ to the recipient and coefficient of relatedness $\left(r\right)$ between the altruist and the recipient is greater in comparison to the fitness cost $\left(C\right)$ to the altruist $\left(Br>C\right)$. It is given that the value of $r$ is $\text{0}\text{.5}$.
