Inclusive Fitness
A concept in evolutionary biology that refers to an individual's genetic success as measured not only by its own offspring but also by the offspring of its relatives, considering the shared genetic heritage.
Altruism
The principle or practice of concern for the welfare of others, often at the expense of one's self-interest.
Reproductive Success

Final Answer :
B
Explanation :
The concept that proposes that genes associated with altruism are selected for if they lead to behavior that promotes the reproductive success of an altruist's close relatives is known as inclusive fitness. This idea was developed by biologist W.D. Hamilton in the 1960s and has been supported by numerous studies of social behavior in animals. Natural selection refers to the process by which certain traits become more common in a population over time due to their beneficial effects on survival or reproduction. The other answer choices (selfish herd, social evolution, and instinctive sacrifice) are not directly related to the concept of inclusive fitness.
