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

Kin selection is a powerful motivation for cooperation in social ________

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

Kin selection is also called inclusive fitness because it should not only be measured by the ________, but all individuals who carry the same genes that underpin the act
