Answer 1

Answer:

d. how much genetic material you share with someone you might help

Explanation:

In family groups or populations there are certain behaviors that might have possitive effects on other individual´s fitness. These behavior are known as prosocial.

Prosocial behavior requires cooperation among individuals that are helping each other. Although sometimes this might implicate a sacrifice of the one that provides the help, in a long-term period the whole group will be beneficiated.

Altruist actions occur when one of the organisms help another one.

To explain these behaviors, Hamilton proposed an explanation for altruism as "inclusive fitness" (1964). According to this, an organism might help another one if this helps beneficiate its genes, that are shared with the organisms that receive help. The concept of inclusive fitness links the evolution of altruism with blood relationship. This means that helping relatives increases the reproductive success of the helping individual, as its genes are represented in the beneficiated relatives. Altruist acts occur to favor close relatives.

The inclusive fitness concept points to the strategy of an organism to ensure the maintenance of its genetic material in the population for a long period of time, even if it requires some kind of harm for itself or is in its detriment.  

In organisms that reproduce sexually, in general, help is directed to the progeny, although it is not always like this.
