Concept explainers

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

1. Definitions of phenotype, genotype, allele, gene, microevolution, macroevolution 2. Know that in humans, most of the genetic variation is observed within populations, and know why that is. 3. Know the 4 processes of evolution (3 neutral + natural selection) 4. Know that evolution isn't progressive and doesn't necessarily lead to more complexity 5. Know that evolution can lead to traits that decrease survival (ex: sexual selection)
1. Would it have made a difference if natural selection had acted on the dominant allele instead of the recessive one? Why or why not Only answer question 1 below is an information about the question. Data result of Testing Hardy-Weinberg Equilibrium with natural selection Chi-square of results from bean model for F1: a. Total of (obs-exp)2/exp = Chi- square value for F1 = 3.1 The resulting chi-squared value is 3.1. b. For a p-value of 0.05 and 2 degrees of freedom, the critical value is 5.99. Our value of 3.1 is smaller than the critical value (5.99), Thus, we cannot reject the null hypothesis. c. The population is in Hardy-Weinberg Equilibrium, and is not evolving or It does conform to null hypothesis. Chi-square of results from bean model for F2: a. Total of (obs-exp)2/exp = Chi- square value for F2 = 6.5 The resulting chi-squared value is 6.5. b. For a p-value of 0.05 and 2 degrees of freedom, the critical value is 5.99. Our value of 6.5 is greater than the critical…
Most new mutations are detrimental, yet rare beneficial mutations canbe adaptive. With regard to the fate of new mutations, discuss whetheryou think it is more important for natural selection to select againstdetrimental alleles or to select in favor of beneficial ones. Which doyou think is more significant in human populations?
1.Describe the ways that gene number or gene position on a chromosome, might be altered? What implications might that have on evolution? 2.What are the conditions that must be met for a population to stay in Hardy-Weinberg equilibrium? What happens if these conditions are not met? 3.What type of selection would most likely benefit heterozygous individuals and which will result in a population losing alleles: directional, disruptive, or stabilizing? Explain. 4.How might frequency dependent selection and the heterozygote advantage help maintain multiple alleles in a population? 5.Describe the theory of evolution by natural selection. Include terms like "excess reproduction, genetically distinct offspring, changing allele frequencies, and adaptive traits".
1. Explain in 200 words how the Darwinian evolution can decrease or increase the frequency of an allele( or a more complex heritable trait, for that matter).
1.) Natural Selection: Of the three genotypes (AA, Aa, and aa), which of the three genotypes will be selected for under the current conditions? In other words, which of the three genotypes will increase in frequency? What if medical science were able to hold off the effects of AIDS for indefinite periods of time so that it became common for people with AIDS to live long enough and well enough to have children. What would this do to the frequency of the resistance allele and the incidence of AIDS? Support your answer. 2.) Even though anti-HIV drugs may prevent evolution towards resistance, can you justify not using anti-HIV drugs if they are available? Your response should consider scientific and ethical perspectives.
1. Why do you think it is necessary for there to be variation in a population in order for evolution by natural selection to occur? 2. Why is it necessary for traits to be inherited for evolution to take place? 3. If a population is already well adapted to its environment, will most mutations be helpful or harmful? Explain.

1. Describe the key components of Natural Selection and explain how the process of Natural Selection can lead to biological change 2. Describe the scientific discoveries of Gregor Mendel and how they help to support Darwin's Theory Of Natural Selection You can research Darwin's Theory of Evolution By Natural Selection to find the answer and the same with Gregor Mendel's scientific discovery
1) What does the term Natural Selection mean? Select one: a.The number and relative frequency of alleles present in a particular population. b.The process through which individuals with certain traits tend to produce more surviving offspring that individuals without those traits. c. Any change in the hereditary material of an organism.
2 2. A survey was conducted for a certain trait (the ability to roll tongue or inability to roll the tongue) in a population. The result shows that 215 of the respondents can roll their tongue and 85 cannot roll their tongue. The picture below shows a person rolling his tongue. Rolling the tongue into a tube shape is often described as a dominant trait. If the dominant allele is represented by R (can roll tongue) and r represents the recessive allele, calculate the phenotypic frequencies, allele frequencies, the expected numbers of the three genotypic classes and the expected numbers of the two phenotypic classes (assuming random mating). Using chi-square test, determine whether or not this population is in Hardy-Weinberg equilibrium. REMEMBER: Genotype Phenotype Can roll tongue Cannot roll tongue HWE term p2 and 2pq q2 RR and Rr rr
