The following genotypes were observed in a population: Genotype: JJ (40), Jj (45), jj (50) a. Calculate the observed genotypic and allelic frequencies for this population. b. Calculate the expected numbers of individuals for each genotype if this population were in Hardy- Weinberg equilibrium. c. Using a chi-square test, determine whether the population is in Hardy-Weinberg equilibrium.
4. Were the expected and observed results similar? Do your results match the prediction for a population in Hardy-Weinberg equilibrium? If not suggest an explanation. 5. What do you expect to happen to the genotype and allele frequencies of the population after running this simulation for 20 generations?
Hi fellow tutor, Please note that from part A-J have been answered. I would like some help please with parts K-N. Thank you Question 5: Applying Mathematical Analysis to Evolutionary Change (17 points) Coloration patterns of a species of snake are controlled by a single gene with two alleles (A= dominant, a=recessive). One population of snakes living in North Carolina was sampled and analyzed using RFLP analysis (restriction fragment length polymorphism), a technique that cuts DNA in specific regions that...
In recent years, some leopard populations have suffered from a loss of habitat. You are part of a research team that is studying the effects that decreased range has on these populations. Your team observed that a portion of one population relocated to the desert and merged with another small leopard population after its own habitat was threatened by deforestation. You have been assigned to lead the study of this new population and look at its gene pool make-up. In...
1. A population of 2000 peppered moths has the following genotypic frequencies:aa: 0.16, Aa: 0.04. AA: 0.80. a. The frequency of the 'a' allele in this population is (show your work for full credit): frequency of the a allele is __ . Calculate the expected genotypic frequencies under Hardy-Weinberg equilibrium. Is this population in equilibrium for genotypic frequencies? Show all your work for full credit. (Do a rough comparison by eye of the observed and expected frequencies to test for...
2.3 Problem 3 The Hardy-Weinberg equation is useful for predicting the percent of a hu- man population that may be heterozygous carriers of recessive alleles for certain genetic diseases. Phenylketonuria (PKU) is a human metabolic dis- order that results in mental retardation if it is untreated in infancy. In the United States, one out of approximately 10.000 babies is born with the disor- der. Approximately what percent of the population are heterozygous carriers of the recessive PKU allele? If you...
HELLO, PLEASE HELP WITH QUESTIONS 8-10 PLEASE PLEASE AND THANK YOU!! PLEASE, I DON'T HAVE ANY MORE QUESTIONS, AND I ASKED THIS 2 TIMES ALREADY AND NO RESPONSE. THANK YOU!!! APPRECIATE IT!! Question Completion Status: BUTTON Questions 5 to 11 are based on the following scenario Question 5: Although the following scenario is hypothetical, it is based on actual facts. African leopards live in a variety of habitats including forests, mountains, grasslands and deserts. Most leopards are light brown with...
13. The following genotype frequencies are observed in a population of 500 individuals. Genotype AA Number of individuals 210 180 Aa aa 110 Total = 500 Answer the following questions about this population (6 points total). a. What is the frequency of the “A” allele? Show your work. (1 point) b. What is the frequency of the “a” allele? Show your work. (1 point) c. Does this locus appear to be at Hardy-Weinberg Equilibrium in this population? Show your work....
For a particular gene associated with a degenerative neurological disorder, you surveyed genotype frequencies in a population and found that 16 people had genotype AA, 97 had genotype Aa, 15 had genotype aa. a) Calculate the allele frequencies. b) Calculate the expected genotype frequencies under Hardy-Weinberg Equilibrium. Use the chi-square test to determine whether the observed number of people with different genotypes and expected number of people with different genotypes are significantly different (at an alpha level of 0.05). What...
Considering the above information, how would you go about completing the following question? Phenotype brown pigmentation brown pigmentation red pigmentation (strawberry leopard) Genotype SS ss Number of leopards 112 98 SS Note: S = dominant allele for brown pigmentation s = recessive allele for red pigmentation (erythrism) Over the next several questions, we will work our way through the process to determine if this leopard population is in Hardy-Weinberg equilibrium (this will include applying the Chi-square goodness-of-fit test). (Before beginning...
