Concept explainers

Genetic Variation

Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.

Quantitative Genetics

Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.

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.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.) 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.

The characteristics of organisms are inherited or passed from parent to offspring. c. Offspring vary among each other about their characteristics, and those variations are inherited d.More offspring are produced than can survive 2.

In your own words, what is the main concept behind theory of evolution by means of natural selection?4. How do you explain evolution to people who believe that it is just a theory?5. Evolution is forever. Do you agree or disagree? Defend your answer.
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. What is the role of variation in evolution – if heterozygosity is reduced, what happens to the potential for evolution? The phenotype (and genotype) of a population is due to a "mosaic" of random and directed processes. Some of these have to do with history; some are related to adaptation, etc. As completely as possible, discuss the role of chance and direction in evolution and in determining the phenotype of a population.
1. What is true of natural selection? The only way to eliminate harmful mutations is through natural selection. Mutations occur at random; natural selection can preserve and distribute beneficial mutations. Natural selection creates beneficial mutations. Natural selection is a random process. All changes saved
