What does kin selection mean?
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 kin selection quizlet?
Kin selection. selection favoring alleles that increase indirect fitness, it is not altruism because it acts to increase indirect fitness.
What is the kin selection theory psychology?
a variation of natural selection that favors behavior by individuals that will increase the chances of their relatives surviving and reproducing successfully (see altruism).
Which best describes kin selection?
Kin selection is altruism that helps to increase a relative’s fitness and consequently the individual’s own fitness. Group selection is a process where an individual’s detrimental behavior is beneficial to the population.
Is an example 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.
Does kin selection apply to humans?
The viscous population mechanism makes kin selection and social cooperation possible in the absence of kin recognition. In humans, altruism is both more likely and on a larger scale with kin than with unrelated individuals; for example, humans give presents according to how closely related they are to the recipient.
What is kin selection example?
The honeybee and other social insects provide the clearest example of kin selection. So any behavior that favors honeybee sisters (75% of genes shared) will be more favorable to their genotype than behavior that favors their children (50% of genes shared).
What is Hamilton’s rule and kin selection?
According to Hamilton’s rule, kin selection causes genes to increase in frequency when the genetic relatedness of a recipient to an actor multiplied by the benefit to the recipient is greater than the reproductive cost to the actor.
What is the purpose of kin selection?
Kin selection is the evolutionary strategy that favours the reproductive success of an organism’s relatives, even at a cost to the organism’s own survival and reproduction. Kin altruism can look like altruistic behaviour whose evolution is driven by kin selection.
Is kin selection selfish?
Kin selection occurs when an individual’s behavior affects the fitnesses of others, usually relatives, that will transmit the behavior non-randomly. However, it can also explain selfish behaviors and is important for understanding conflicts between individuals.
Why is kin selection important?
Kin selection is important because it can explain altruistic behavior, such as in workers of the social insects. However, it can also explain selfish behaviors and is important for understanding conflicts between individuals.
