1. Fixation of Dominant Alleles Start with a population that has a gene with two alleles (A and a) with classical Mendelian dominance that are at equal frequency (p0.5. q 0.5). Assume this first generation is at hardy Weinberg equilibrium. Calculate the genotype frequencies AA- a. Aa b. Now assume some environmental change that makes the recessive phenotype completely unfit (fitness- 0). Calculate the allele frequencies and genotype frequencies in the second generation. (Hint: Your calculations might be easier if...

6. Which of these conditions will lead to evolution by natural selection? a. Heavy metal pollution reduces reproductive success of all phenotypes of green algae in the pond. b. Variation among individuals is not genetic; instead it results from learned behavior or physiological environmental responses. c. Introduction of an exotic predator species results in one native prey phenotype evading predation while other phenotypes get eaten. d. Individuals of the population are clones (genetically identical). 7. Which one is used as...

In a population of mice a particular locus has two alleles A1 (dominant) and A2 (recessive). There are 126 A1A1, 167 A1A2 and 88 A2A2. Is this population in Hardy-Weinberg equilibrium (3 pts)? In a population of Gragons, there are 3151 A1A1, 1678 A1A2 and 2014 A2A2 individuals. If the environment changes so that the homozygous recessive genotype suffers a reduction of fitness where its fitness is now 0.73, but the other genotypes are unaffected, what will be the frequency...

I need help with questions 1 through 2, thank you!
The Esatina salamanders (Ensatina eschscholtzii), shown above, live along the West Coast of North America from Vancouver to Baja California. We will be focusing two populations: 1. individuals that live in Northern California and represent a more ancestral population 2. individuals that live in Southern California. Researchers have found that these all individuals of this salamander species have two color phenotype, either red or blotchy. Genetic analysis has shown that...

You have journeyed to the center of the earth, and discovered the lost population of Tyrannosaurus rex. Naturally, the first thing you do is study evolution in their population. 10) You identify the Ferocity locus, and notice that the Tyrannosaurs differ in fitness depending on their genotypes (FF, Ff and ff) and the associated phenotypes, and the associated trait is heritable. a) What evolutionary mechanism is relevant to this scenario? (2 points) b) FF and Ff individuals have the same...

BIOL 1020 Homework Evolution & Natural Selection 4 NATURAL SELECTION: 1. In your OWN words, explain what natural selection is. What is required? What is the result? 2. True or false? For natural selection to work, a population must have genetic variation. Explain your answer. 3. List three sources of genetic variation in a population. Identify which sources are most important for asexually reproducing organisms. Which method is most important for sexually reproducing organisms? 4. List three mechanisms which cause...
