BIO 415 Discussion Random Genetic Drift Project Computer Simulations of Evolutionary Genetic Mechanisms Part A Graph for A. (N=16) (1.) Summarize the differences in one sentence. Then explain the differences in terms of heterozygosity, allele fixation and allele loss in one complete and concise paragraph. a. My histogram is similar to Buri’s as it is shaped like the letter U. It indicates that allele A1 is almost equally as likely to drift towards loss or fixation, with a ratio of loss to fixa...

T/F: Species diversity increases as you approach the equator correct answer: True What are possible reasons why more species occur near the equator correct answer: - More time without geological disruptions (e.g., glaciers) - More niches - Climatic stability - Greater biological productivity What is speciation correct answer: The formation of two species from one ancestral species What factors lead to speciation correct answer: - natural selection - sexual selection - genetic d...

Why might Pasteur's experiment be inconclusive? - Answer The swan-necked flask broth may not support cell growth, or the broth was poisoned. Experiment did not confirm hypothesis that all cells come from pre-existing cells Why are replicates important in experiments? - Answer To ensure that results were not achieved by random chance What is the definition of a replicate? - Answer Unit that shares a common thing (4 mice in one cage = 1 replicate) What does the law of succession suggest?...

Interpret this statement: Extinct fossil species are typically succeeded by similar living species - Answer Extinct and living forms represent ancestors and descendants Which is an example of developmental homology a) gene content b) similar organismal structures c)vestigial traits d) similar embryonic traits - Answer d) Which is not one of Darwin's 4 Postulates: a) Individuals in a population vary in their traits b) These differences are not heritable; they are not passed onto offs...
