inclusive fitness
The total effect an individual has on multiplying its genes by producing offspring AND by helping close relatives to produce offspring
three key variables in an altruistic act

–coefficient of relatedness
Natural selection favors altruism when what?
what is this rule called?
- benefit multiplied relatedness exceeds cost
- rB > C
- Hamilton’s rule
