Which of the following statements regarding selection is true? Incorrect answer - selection will always result in a change in allele frequencies. Correct Answer - The direction and magnitude of allele frequency change due to selection can be predicted. Question: Please explain in detail why the correct answer is correct and please explain why the incorrect answer is not correct.
Which of the following statements about genetic fitness and/or selection is false? Group of answer choices Individuals with low fitness have greater selection coefficients Fitness involves both relative viability and reproductive success Individuals with high fitness have greater selection coefficients Selection against recessive alleles tends to be slower overall than dominant alleles because of the survival in heterozygotes
How can negative traits that don't show up until old age continue in populations? (Why aren't they eliminated through natural selection?) As part of your answer, provide an example.
Sickle cell anemia is maintained in human populations because individuals with a single copy of the sickle cell allele have resistance to malaria but lack the health problems of individuals with two copies of the allele. Variation at the sickle cell locus is maintained by which of the following? Group of answer choices A. heterozygote advantage B. random change in allele frequency C. mutation selection balance D. frequency dependent selection
The Hardy-Weinberg principle states that, in a large population, the proportion of each allele will do which of the following if there are no environmental forces on the population? increase for recessive alleles decrease for dominant alleles remain the same increase for dominant alleles
Godfrey Hardy and Wilhelm Weinberg stated the principle of equilibrium to describe the genetic makeup of a population. The theory, also known as the Hardy-Weinberg principle of equilibrium, states that a population’s allele and genotype frequencies are inherently stable. Which of the following phenomena could disrupt this equilibrium? Mutations Selection pressure Migration All of the given choices
When selection favors homozygotes over heterozygotes it is likely that... Incorrect answer - both alleles will be maintained in the population at frequencies different from those predicted by Hardy-Weinberg principles. Correct Answer - genetic diversity will decrease as one of the alleles will become fixed within the population. Question: In detail, please explain why the correct answer is correct and also please explain in detail, why the incorrect answer is not correct.
American cat breeders are trying to establish a new breeed of cat with unusual, curled-back ears, to be known as the "curl cat." Suppose you found a curl cat and wanted to secretly start your own population. How would you determine whether the curl allele is dominant or recessive? How would you establish and maintain a true breeding population based on whether the allele is dominant or recessive?
Which of the following is true about natural selection? Group of answer choices it acts on individuals it typically does not involve changes in genotype frequencies in a population it involves individuals willfully changing their genotype and/or phenotype in order to become better matched to their environment and leave more offspring it is a random process it involves humans increasing the frequency of desirable traits in a species by selecting which individuals breed
You discover that there are 4 alleles for the “w” gene that determines wing shape in flies. Is this a violation of Hardy-Weinberg model? Group of answer choices Not if one of the alleles is present only in females. Not if the trait is determined by sexual selection. Not if all four alleles are present in the population. Yes, because Hardy-Weinberg can only be applied to genes with 2 alleles. None of the answers shown are correct.
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.
Which statement accurately complete the following sentence: “If selection favors a new allele within a population, over time that allele should increase in frequency, however, genetic drift..” Correct Answer - can weaken selection, which occurs to a higher degree in smaller populations compared to larger populations. Incorrect Answer - will increase and strengthen selection on the allele and cause the allele to go to fixation faster. Question: Please explain in detail why the correct answer is correct and please also explain why the incorrect answer is not correct.
