Is kin selection inclusive fitness?
Kin altruism can look like altruistic behaviour whose evolution is driven by kin selection. Kin selection is an instance of inclusive fitness, which combines the number of offspring produced with the number an individual can ensure the production of by supporting others, such as siblings.
What are some examples of kin selection?
The honeybee and other social insects provide the clearest example of kin selection. They are also particularly interesting examples because of the peculiar genetic relationships among the family members. Male honeybees (drones) develop from the queen’s unfertilized eggs and are haploid.
What is Hamilton’s rule and how is it related to kin selection and the idea of inclusive fitness?
Hamilton’s rule is a central theorem of inclusive fitness (kin selection) theory and predicts that social behaviour evolves under specific combinations of relatedness, benefit and cost.
What is B in Hamilton’s rule?
B is the benefit (in number of offspring equivalents) gained by the recipient of the altruism, ℂ is the cost (in number of offspring equivalents) suffered by the donor while undertaking the altruistic behaviour, and r is the genetic relatedness of the altruist to the beneficiary.
How does kin selection work?
kin selection, a type of natural selection that considers the role relatives play when evaluating the genetic fitness of a given individual. Kin selection occurs when an animal engages in self-sacrificial behaviour that benefits the genetic fitness of its relatives.
What is the meaning of kin selection?
What does relative fitness mean?
Models of Selection One can speak of the fitness of an individual or a genotype or an allele. Fitness can also be measured on a relative scale: Relative Fitness = The average contribution to the offspring generation relative to the contribution of another type.
How is kin selection different from altruism?
The main difference between kin selection and reciprocal altruism is that kin selection favors the reproductive success of the other relatives even at a cost to the organism’s own survival and reproduction. Furthermore, kin selection uses shared genes, while reciprocal altruism does not use shared genes.
