- A form of learning disabilities and speech impairment results from a recessive mutation in the HERC2 gene. The next 4 questions are about this mutation. In a small Amish village in Ohio, about 5 per 1000 births are affected with this disorder. Assume Hardy Weinberg equilibrium. What is the frequency of the dominant WT HERC2 allele in this small village? A form of learning disabilities and speech impairment results from a recessive mutation in the HERC2 gene. The next 4 questions are about this mutation. Part a: In a small Amish village in Ohio, about 5 per 1000 births are affected with this disorder. Assume Hardy Weinberg equilibrium. What is the frequency of the dominant WT HERC2 allele in this small village? a)0.005 b)0.995 c)0.07 d)0.93 Part b: What is the estimated total number of homozygous dominant individuals in this village of 1000 people? a) 70 b) 930 c) 860 d) 140The following questions refer to this information: In the year 2500, 5 male space colonists and 5 female space colonists from Earth settle on an uninhabited Earthlike planet in the Andromeda galaxy. The colonists and their offspring randomly mate for generations. If 4 of the original colonists died before they produced offspring, the ratios of the genotypes could be quite different in the subsequent generations. This is an example of what kind of selection?After many generations, the population on this planet has an unusually high frequency for the incidence of retinitis pigmentosa (a hereditary disease that impacts night vision), relative to Earth’s population. This is most likely due to what?How Can We Measure Allele Frequencies in Populations? Drawing on your newly acquired understanding of the HardyWeinberg equilibrium law, point out why the following statement is erroneous: Because most of the people in Sweden have blond hair and blue eyes, the genes for blond hair and blue eyes must be dominant in that population.
- How Can We Measure Allele Frequencies in Populations? The MN blood group is a single-gene, two-allele system in which each allele is codominant. Why are such codominant alleles ideal for studies of allele frequencies in a population?Dunkers are part of a religious group which originated from 27 families that emigrated from Germany to the USA in the XVIIIth century. Dunkers only mary between themselves. The frequency of the M allele in the MN blood group system is 0.65 among Dunkers while it is 0.54 in both German and American populations. a) How can you explain this observation ? Is this due to genetic drift, natural selection, or inbreeding?A population consist of 7 mice. For the coat trait, there are only two alleles: brown B and white (b). BB and Bb mice are brown; bb mice are white. In the population's gene pool, there are 7 white alleles(b). a) what is the frequency of the brown allel in the population? b) what do you predict the frequency of the bb genotype will be in the next generation if no evolution takes place in the population?
- The following table provides phenotypic data for a population of mammoths living in cold environments based on fossil and DNA evidence. Based on this data and your knowledge of natural selection, which explanation best explains the trends seen in the data? Individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offspring. Individuals within this population of mammoths tend to only mate with individuals that have thick fur. This population of mammoths appear to be in Hardy-Weinberg equilibrium since no allele frequencies are changing over time. Individuals with thick fur migrated into the population of mammoths, increasing the proportion of these individuals.A researcher studies two types of fly populations. Population A have stubby bristles which are both shorter and blunter than population B. This is because the flies are homozygous for a certain allele for the stubble gene which affects bristle length. These flies are ebony coloured with black bodies. This is because they are homozygous for a certain allele for the ebony gene that affects body colour. Population B have longer and tapered bristles than population A and are not stubbly in appearance. This is due to them being homozygous for a different allele for the gene that affects bristle length to population A. These flys are not ebony coloured and have brown bodies. This is due to them being homozygous for the gene that affects body colour. The researcher crosses parental flys (P1) from population A with those from population B and counts the number of offspring that have stubble and non-stubble bristles, and the number of offspring that are ebony-coloured and non-ebony-coloured…A researcher is studying two fly populations. Population A have stubbly bristles that are shorter and blunter than population B and are ebony coloured with black bodies. This is because they are homozygous for a certain allele for the stubble gene which affects bristle length and homozygous for the ebony gene which affects body colour. Population B have longer tapered bristles than population A and are not stubbly in appearance. They are not ebony and have brown bodies. This is because they are homozygous for a different gene that affects bristle length to population A and are homozygous for the gene that affects body colour. Table 1: F1 ebony flies - 0 F1 non-ebony flies - 560 F1 stubble flies - 560 F1 non-stubble flies - 0 Draw two separate Punnett Squares to illustrate the P1 cross - one for the stubbly alleles and one for the ebony alleles showing the individual gametes of each parent and the combination in the resulting F1 offspring.
- In New Zealand you begin to study the relationship between snails and their trematode parasites. You found that the parasites cause cyclical patterns of selection on the snail populations, and vice a versa, such that snails with rare genotypes typically survive better compared to those that have more common genotypes. In the ten years you’ve been sampling, you notice that the two alleles cycle between being rare and common from year to year. What pattern of selection did you observe? a. selection against the dominant allele b. selection against the recessive allele c. frequency-dependent selection d. overdominanceThreatened species often have small, isolated populations where mating between relatives occurs. Let's assume one of these threatened species has a disease controlled by a gene that has two alleles A and a. Only individuals with two copies of the "a" allele have the disease and die before reproducing. Question: What are the effects of inbreeding on the frequency of the "a" allele, and the frequency of the disease in the population?Taita thrush is an endangered bird endemic to Kenya. Galbusera and colleagues genotyped Taita thrush individuals from three populations at microsatellite markers. You have a museum specimen, and you want to determine which population it most likely to came from. You determine that the museum specimen is homozygous for two microsatellite alleles (A₁ and B₁). The frequencies of each allele in each population are shown in the table below. Population Chawia Mbololo Allele A₁ 0.6471 0.7063 0.6204 Allele B₁ 0.2917 0.1863 0.4000 Ngangao What is the probability that your individual comes from each of the three populations?
