Question

Be sure to answer all parts. Part 1 out of 2 The concept of kin selection suggests that a behavior lowering an individual's fitness can increase in frequency in a population if the behavior increases the chances that a relative will be able to reproduce and pass on shared genes. Obviously individuals don't actually perform any calculations to determine whether an altruistic behavior is worthwhile. It is possible to do such calculations; Hamilton's rule allows the quantification of a risk:benefit ratio of a particular altruistic behavior. Hamilton's rule takes into account the relatedness of the altruist to the relative being benefited by the behavior (a value called r), and the perceived benefit to the relative of the altruistic behavior (a value called B) and compares that to the cost to the altruist (a value called C). A gene responsible for an altruistic behavior will be positively selected for if rВ is greater than C. To begin to use Hamilton's rule, you first need to determine the relatedness between the altruist and the recipient of the altruistic behavior. What is the percentage of genes shared between yourself and your cousin? Next part

Answer 1

Answer: 25% & quues are shared Between Yourself and your granddaughter. Consider yourself of 'Mother, the daughter Recieves half of the genetic Material from Mother. So, that the Half o the genes Ave shared Between the Mother and daughter, i..., Mother's grond daughter. So, the Mother Bilomes a grond mother. Similarly, this daughter gave. Half dher ques to her daughter [Mothers gronddoughter]. It is possible that half of the genetic Material she (grondoughter] took from my doughter is Actually originated from her grandmother (Yourself). So, the relat dness Colllicient with Mother (YoursuF) and grandaughter is one-half of one-half, that is, (1/2) + (1/2) or 1/4.

thus, 25% of quis Ari Shared Between Mother and grond daughter Im guneral, your coefficient of relatoniss (percentage of gnus Shared with your level- n oncestor is 1/2n. the concept Becomes clearer with the diogram given below! You daughter [level 1 descendont] grond daughter (level 2 descendont]
