Reseаrchers mоve а set оf sаlamanders tо a larger island with shrubs. They intentionally choose salamanders with three body sizes to move: small, medium, and large. They wanted to understand the strength of natural selection acting on body size. Use the table below to calculate the selection coefficient for the large phenotype. Phenotype: Large Medium Small Chance of survival to mating: 25% 50% 10% Number of offspring if survive: 10 20 10 Fitness (average for an individual with that phenotype): 0.25 x 10 = 2.5 0.5 x 20 =10 0.1 x 10 = 1 Relative fitness: ? ? ? Selection coefficient: ? ? ?
