Question

Please, answer this question in detail.

Imagine there are a group of bluegills that lay their eggs in the same general area of a pond and we are interested in whether or not these individual engage in regular helping behaviors. On average, the fish within this area share approximately a quarter of their genes. If they engage in defense of their neighbors nest, those nests produce roughly 200 more offspring than undefended nests. By defending the nests, their energetic output is diminished just slightly, resulting in the loss of 40 potential offspring. Would we expect this behavior to continue over time?

Answer 1

It depends on the concept of kin selection theory of Hamilton. According to this if inclusive fitness(Sum total of fitness of all reipient and donr) is greater than individual fitness then kin selection can occur.
