- Give written answer with explanation and conclusion A population of rabbits may be brown (the dominant phenotype) or white (the recessive phenotype). Brown rabbits have the genotype BB or Bb. White rabbits have the genotype bb. The frequency of the BB genotype is 0.35. Assuming that this population is in Hardy-Weinberg equilibrium, what is the frequency of the B and b allele respectively?60 individuals have the genotype AA28 individuals have the genotype Aa12 individuals have the genotype aaWhat is the frequency of the A allele?Think of how many alleles in total?hint: add up the number of A alleles in this population: AA= 60+60 and Aa= 28.Add those together and divide by the total number of alleles.Which statement best summarizes why genetic drift tends to impact small populations more than large populations? A. Small populations have a heterozygote advantage because heterozygotes are more common than homozygotes. B. Small populations have a smaller gene pool, so random changes influence them more. C. Small populations have a relatively large gene pool, so the founder effect stabilizes their alleles.D. Small populations tend to experience directional selection, making one phenotype more common.
- A student sampled a population of fruit flies in which the percentage of homozygous recessive white eyed males (rr) was 70%. Calculate a) Allele frequencies for white and red gene b) Genotypic frequencies in case of inbreeding of the population in the next generation1) 10,000 individuals are sampled from a population and are found to display one of three blood types: AA with 6800 individuals, AB with 2800 individuals and type BB with 400 individuals. a) What is the frequency of each genotype in the population? b) What is the frequency of the A allele? c) What is the frequency of the B allele? d) If the next generation contains 25,000 individuals, how many would have blood type BB, assuming the population is in Hardy-Weinberg Equilibrium?Imagine the unlikely case that the 11 individuals represented in the gel image above were truly representative of the population. If 1 is the largest and 7 the smallest allele; what is the frequency (f) of allele 3? Give your answer as a percentage, to one decimal place, do not include the % symbol.
- Under genetic drift, if an allele’s frequency is 1%, what is the likelihood that it will be lost from the population? part B; Construct a graph that describes the likelihood of fixation of a particular allele, for a small population that is under Wright-Fisher genetic drift. Don’t forget to label axes completely.A. What does it mean if an allele is “fixed”? B. Explain one reason why EVEN if an allele is undergoing strong positive selection it may not become fixed in the population.The frequency of two alleles in a gene pool is 0.19 (A) and .81 (a). Assume hardy-Weinberg equilibrium Calculate the percentage of heterozygous individuals in the population Calculate the percentage of homozygous recessives in the population
- You sample a population of butterflies and find that 42% are heterozygous for a particular gene. What would be the frequency of the recessive allele in this population? Group of answer choices 0.42 0.28 0.58 0.21 Allele frequency cannot be determined from this information.Can two populations have the same allele frequencies but different genotypes frequenciesGive typing answer with explanation and conclusion Which of the following statements is false? Question 5 options: A) When insect populations are attacked with pesticides, the populations increase their mutation rates so that they can develop pesticide-resistant alleles. B) Small populations have smaller gene pools than larger populations. C) The fittest members of a population leave more offspring than less-fit individuals. D) Natural selection is responsible for most adaptive changes in populations
