For each of the following: What would you expect to be the most important evolutionary force acting between this generation and the next affecting the genetic composition of the populations (for these scenarios for a specific locus, we are concerned only with that locus and/or phenotype)? a) A population of bacteria that was started from a single cell 1 generation ago? b) A population of LL individuals that comes into close contact with a population of LL, Ll, and ll individuals. Assume the two populations exchange 10% of their populations through migration and the three genotypes do not differ in fitness? c) A population in which the absolute fitness of each of three phenotypes are: blue = 100, blue-orange = 90, and orange 90 and phenotypes are determined by the environment, not genetics? d) A population in which a mutation produces a new allele that increases the individuals that have that allele to have a higher probability of surviving to reproductive age (assume a 5% increase). Assume the mutation entered the population 1 generation ago and Ne = 100,000?
