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...

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?...
