Summary Introduction

To determine: The differences between kin selection and altruism. The ways by which kin selection is in accord with the notion of inclusive fitness.

Introduction: If everything else is considered to be equal, then brothers who share half of their alleles are more likely to aid one another rather than a cousin with whom they share only one-fourth of the alleles. The hypothesis proposed on the basis of this genetic explanation for altruism and cooperation is called kin selection.
