Bio 414: Evolutionary Analysis Ch. 6 question and answers graded A+ 2023Restate the theory of evolution from a "population genetics" standpoint. - correct answer Changes in the relative abundance of traits in a population can be tied to changes in the relative abundance of the genetic variants that influence them (integrates evolution by natural selection with Mendelian genetics) Why is it important to establish a null model for how genes frequencies (like the delta 32 CCR5 allele) should behave in populations? - correct answer Specifics, under simplest possible assumptions, what will happen across generations to the frequencies of alleles and genotypes. Population genetics begins with a model of what happens to allele and genotype frequencies in an idealized population. What is a population? - correct answer A group of interbreeding individuals and their offspring. For a gene in question, how many gene copies does the gamete of a diploid species have? - correct answer One gene copy For a diploid species, how many gene copies does an adult have for any particular gene in question? - correct answer Two copies. Simulate 50 zygotes using figure 6.2 and be prepared to report your allele frequencies in class. How did your simulation differ from the stated allele frequencies of .6 for A and .4 for a? (follow the example in the book to calculate the allele frequencies). - correct answer -14 AA adults make 140 gametes: 140 allele A 28 Aa adults makes 280 gametes: 140 A; 140 a 8 aa adults make 80 gametes: 80 a 0.44 a frequency; 0.56 A frequency Did your simulated population in question 6 evolve? - correct answer Yes
