Document Summary
Remember, inheritable traits can be morphological, behavioral, physiological. Does a population evolve: 3 types of mutation: lethal, neutral, useful, we can track allele frequencies for 1 or more genes. Tell what the following represent: p q p2. If the population is in equilibrium, then no microevolution is occurring: examples, 4% of a population has severe form of sickle cell anemia. In a particular class of 65 students, 43 can roll their tongue; 22 cannot. B-6 what % of the class is a tongue-roller? answers: b-1: 22/65 = 0. 338; square root of this = 0. 58 = q. B-3: 2pq = 2 x 0. 42 x 0. 58 = 0. 48. B-6: 66: in flies, a = normal wing, a = vestigial wing. In a population, 9% of the flies have vestigial wings. The flies are then reared in a windy environment. Later you note that 25% of the flies have vestigial wings. Why or why not? answers: 7-a=0. 3, 7-b=0. 42, 7-c=0. 5, 7-d=0. 5: causes of microevolution.
