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 (-5[1])from the emergence of (*) spiteful genes. One behavior is favored if “this parameter times benefit minus cost is greater than zero,” per Hamilton’s rule. In a pedigree, (-5[1])this parameter equals one-eighth (-5[1])for cousins and one-half for full-siblings. (10[1])For 10 points, what parameter denoted r measures the genetic similarity between individuals? (10[1])■END■ (10[1]0[1])

ANSWER: relatedness [accept coefficient of relatedness or coefficient of relationship; accept negative relatedness; accept consanguinity; prompt on r until “r” is read; reject “coefficient of inbreeding” or “COI” or “F”]
