Based on the theory of kin selection, choose the correct statement:
1
A gene for altruism will spread in the population if the act of altruism increases the actor's gene in the next gene pool only through direct fitness.
2
A gene for altruism will spread in the population if the act of altruism increases the actor's gene in the next gene pool only through indirect fitness.
3
A gene for altruism will spread in the population if the act of altruism increases the actor's gene in the next gene pool through direct or indirect fitness.
4
Altruistic behaviour reduces the fitness of the trait bearer so a gene responsible for altruism cannot spread in a population and will be maintained at a very low frequency.
