Results of Microevolution exercise in class The effect of microevolution on our very small sample population is an excellent example of how Genetic Drift  (bottleneck) can affect the future gene pool and distribution of alleles.  Trait Ear lobes Class Participating individuals = 90 EE, Ee = 72 (domitraitsnant, free-hanging earlobes) (80%) ee = 18 (recessive, attached earlobes) (20%) Starting population = 23 (5 males and 18 females?) (26% of known sample) 18 individuals were EE or Ee (79%)   5 individuals were ee (21%) The distribution of phenotypes is nearly identical to the  representative class population. Post-catastrophic population = 5 individuals (ALL female!!) 2 females were EE or Ee (40%) 3 females were ee (60%) Hardy Weinberg Participating Individuals Equilibrium = E 2   + 2Ee + e = 100%   OR   p 2   + 2pq + q = 100%    (E  =  p,   e  =  q)
