Step by step
Solved in 2 steps
- Discuss how the finite size of populations means that new mutations eventually will be either lost or fixed.The forward mutation rate for piebald spotting in guinea pigs is 8 × 10-5;the reverse mutation rate is 2 × 10-6. If no other evolutionary forces areassumed to be acting, what is the expected frequency of the allele forpiebald spotting in a population that is in mutational equilibrium?Why is a balancedfrequency of different allelesof a gene in a population moreuseful for the survival of thatpopulation facingenvironmental changes?
- Hippogriffs can have black fur or gray fur. However, there is a high rate of mutation from black alleles into gray alleles. In a population of 1000 hippogriffs, if there are 600 alleles for black fur and the forward mutation rate (ie., from black to gray) is 10%, approximately how many black alleles should be expected in the next generation? Group of answer choices 60 540 300 10 660assume that the new allele is not strongly deleterious and that it will ultimately become fixed (replace the original allele) in the population. tell the story of how and why the new variant becomes fixed. , be sure to state its frequency at three or more points in time, measured in generations.Define gene mutation Group of answer choices A. the process whereby organisms better adapted to their environment tend to survive and produce more offspring. B. the introduction of genetic material (by interbreeding) from one population of a species to another, thereby changing the composition of the gene pool of the receiving population C. variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce. D. A rare and random change in a gene that can be bad or benef icial depending on the environment .
- Suppose that a population is at equilibrium between mutation and selection for a deleterious recessive allele, where s = 0.5 and μ = 10−5. What is the equilibrium frequency of the allele? What is the selection cost?A) Distinguish genetic drift from gene flow in terms ofhow they each occur and their implications for futuregenetic variation in a population.B) Explain the importance of the bottle neck effect inconservation biology of endangered species.Scientists are studying two populations of the same species of sea turtle. One population is quite small, with only 18 individuals, and the other is much larger, with 147 individuals. If a genetic factor such as a mutation were introduced to both populations at the same time, what could scientists predict about the impact?
- Imagine a huge population with a gene that has ten functionally equivalent, neutral alleles. a small but genetically representative group of individuals from the population is transported to an island, forming a small population. what will likely happen over time and why?In the population of insects shown, insects with spots have the genotype Aa or AA and bugs with no spots have the genotype aa. Which argument best supports the phenomenon shown in the diagram? There was an increase in the fitness of the gene A. There was an increase in the fitness of the gene a. There was an increase in the mutation rate of gene A. There was an increase in the mutation rate of gene a.The magnification of genetic drift as a result of natural events or catastrophes is _____; _____ is the flow of alleles in and out of a population due to the migration of individuals or gametes.
