The Selfish Gene Question Set 2 Chap 6. Genesmanship 1. What is "Green Beard Altruism?" Is it an evolutionary stable strategy? 2. How does Dawkins suggest that a gene could "recognize" copies of itself in other individuals? 3. How is that parents and children certainly share half their genes, but siblings only share half their genes on average ? 4. How do you calculate the coefficient of relatedness? 5. What is the coefficient of relatedness for first cousins? Aunt and niece? Grandfather and granddaughter? 6. Dawkins (p.93 ) says a suicidal gene would increase in frequency if it caused the death of its bearer but saved the life of five brothers, but not if it saved the life of only five cousins. Why? 7. Why should grandparents be more altruistic toward grandchildren than grandchildren to grandparents? 8. How can all this work if individuals are not conscious of their coefficient of relatedness? 9. What does Dawkins mean by an "evolutionary arms race?" Can you think of other examples?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
