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.

Changes in the Population
There are four major types of selection when it comes to changes
being made in an ecosystem.
Natural Selection is the process of selecting traits that makes an
organism most successful in its given environment.
Directional Selection is when individuals at one end of the curve
have higher fitness than individuals in the middle or at the other end.
Stabilizing Selection is when individuals near the center of a curve
have higher fitness than individuals at either end.
Disruptive Selection is when individuals at the upper and lower ends
of the curve have higher fitness than individuals near the middle.

You are asked to assess whether a population of endangered salamanders can adapt to warming climate in their preferred habitat. The salamanders vary at a locus that determines adaptation to temperature, and the warming climate creates selection favoring one of two alleles at that locus. Drawing on what you know about natural selection and genetic drift, what information would you need to know about the salamanders to determine whether the allele that improves their adaptation to warmer climates will become fixed in the population? Strictly no plagiarism.
Which of the following is not true of natural selection? (a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a population
If a populations allele and genotype frequencies remain constant from generation to generation, (a) the population is undergoing evolutionary change (b) the population is said to be at genetic equilibrium (c) microevolution has taken place (d) directional selection is occurring, but only for a few generations (e) genetic drift is a significant evolutionary force
In which of the following pairs do both evolutionary processes introduce new genetic variation into a population? a. natural selection and genetic drift b. mutation and gene flow c. natural selection and gene flow d. gene flow and genetic drift
Which of the following is likely to be observed if there has been a strong positive selection on a particular genetic locus within a population? Group of answer choices There will be a lot of variation in DNA surrounding the genetic locus in question within the population. There will very little variation in DNA surrounding the genetic locus in question within the population. You will see very low frequencies of the genetic locus in question
Which statement is accurate about natural selection? It is a biological process that prevents species from adapting to significant changes in their environments. It is a biological process that leads a population to have a widespread expression of an advantageous trait. It is a biological process that allows a population to have a competitive advantage in many environments. It is a biological process that causes certain traits to be expressed less with each subsequent generation.
In which of these examples can natural selection act on a trait and cause the population to evolve? A population that is faced with extinction but has no genetic variation A population where a lot of individuals have mutations, but none of the mutations relate to fitness A population with no genetic variation, but where individuals have very high numbers of offspring A population where a few individuals have mutations that allow them to develop traits for producing more offspring than other individuals
Which of these conditions should completely prevent the occurrence of natural selection in a population over time? Group of answer choices The population size is large All variation between individuals is due only to environmental factors The population lives in a habitat where there are no competing species present The environment is changing at a relatively slow rate
In the modern reckoning of evolution by natural selection, what is the most important feature that allows an allele to be more represented over time in a population? The allele makes the organisim stronger. The allele allows the organisim to produce more breeding offspring. The allele allows the organisim to eat more readily. The allele allows the organsims to escape predators readily.
Starting from a single wild canine species, humans have developed hundreds of breeds of domestic dogs. Which of the following statements is supported by this observation? 1) Natural selection had not occurred very frequently in the wild dog populations. 2) There was enough heritable variation in the wild canine species to create a variety of features. 3) Heritable variation is low; otherwise the there would be more wild dog species. 4) Most of the variation in domestic dog species is a result of variation in nutrition and training.
Natural selection is based on all of the following except individuals who survive longer tend to have more offspring than those who die young genetic variation exists within populations Individuals adapt to their environments and, thereby, evolve populations tend to produce more offspring than the environment can support the best adapted individuals tend to reproduce more
Imagine a population of beetles living in someone's backyard. The beetles inhabit several different areas of the backyard, including the garden, patio, and storage shed. One day, the owners spray the garden with insecticide, killing off about half of the beetle population. What effect will this have on genetic variation and what evolutionary force is this an example of? Group of answer choices Reduces variation; genetic drift Increases variation; natural selection Reduces variation; natural selection Increases variation; genetic drift
