Students created a model showing one possible mechanism for speciation in which a geographic barrier separated one large population into two smaller populations, A and B. The warmer temperatures will lead to a drier environment, so the plants will no longer produce enough nectar to attract the pollinators. In an experiment, the scientist creates two groups of twenty highly inbred mice. Populations with little genetic diversity are less likely to contain individuals that can withstand different selective pressures. WebStatistics and Probability questions and answers. The geneticist determines the genotypes for a particular trait of all of the mice in the population during generation 1 and then removes all of the mice with the genotype aa. C. The plant species will flower earlier in the spring in response to rising temperatures before the arrival of the pollinators, so seeds will not be produced. Dark coat color provides camouflage to mice on the flow; therefore, mice with dark coats predation rate in that habitat. The darker backgrounds conferred a selective advantage to the black variety, as described by natural selection. The two populations will show significant genetic differences because the founder effect will result in significant losses in diversity in the smaller population. Start each population with genetically identical bacterial cells from a single culture to make sure that the initial genetic variation in all of the populations was exactly the same.
