Round 5: Tossup 5

This parameter is plotted along a line running from mu to A in a “geometric” method developed by Alan Grafen. This parameter and competition are assumed to be locally enhanced for a viscous population in a method of estimating this parameter named for Goodnight and Queller. According to one theory, unusual asymmetries in this parameter within a population drive the evolution of eusociality. A less-than-average “negative” form of this parameter often arises from the emergence of (*) spiteful genes. One behavior (-5[1])is favored if “this parameter times benefit minus cost is greater than zero,” per Hamilton’s rule. (-5[1])In a pedigree, this parameter (-5[1])equals one-eighth for cousins and one-half (10[1])for full-siblings. (10[1])For 10 points, what parameter denoted (-5[1])r measures the genetic similarity between individuals? ■END■ (10[4])
