C represents the ________cost to the individual performing the behavior
Selection
Hamilton's theory of kin selection predicts that altruistic behaviors will be favored by ________ if the costs of performing the behavior are less than the benefits to the receiver multiplies by the relatedness of the actor and recipient.

Selection
Kin ________is a powerful motivation for cooperation in social interactions
Cooperation
Kin selection is a powerful motivation for ________in social interactions
Interactions

Altruism
Kin selection is a solution for the conundrum of ________because natural selection does not take place at the individual level— it takes place at the level of traits,which are the genes that underpin the action
Individual
Kin selection is a solution for the conundrum of altruism because natural selection does not take place at the ________level— it takes place at the level of traits,which are the genes that underpin the action
Traits
Kin selection is a solution for the conundrum of altruism because natural selection does not take place at the individual level— it takes place at the level of ________,which are the genes that underpin the action
Genes
Kin selection is a solution for the conundrum of altruism because natural selection does not take place at the individual level— it takes place at the level of traits,which are the ________that underpin the action
Action
Kin selection is a solution for the conundrum of altruism because natural selection does not take place at the individual level— it takes place at the level of traits,which are the genes that underpin the ________
Inclusive
Kin selection is also called ________fitness because it should not only be measured by the individual, but all individuals who carry the same genes that underpin the act
Fitness
Kin selection is also called inclusive ________because it should not only be measured by the individual, but all individuals who carry the same genes that underpin the act
Individual
