- Nieman-Pick Syndrome involves a defective enzyme, sphyngomylinase. It is usually fatal before the age of 3. The defective allele frequency is 0.01 in Ashkenazi populations. Let’s call the healthy allele A, and the lethal allele a. a) What is the frequency of allele A? Assuming Hardy-Weinberg equilibrium, how many people do you expect to have the three genotypes in a population of 10,000? b) AA:_______ c) Aa:________ d) aa:_________Under the above conditions of reproductive discrimination against those with attached earlobes, if the population in this next generation is still 500,000 people, then the new genotypic frequencies will be: Homozygous dominants, unattached ear lobes: 0.34 Heterozygotes, unattached ear lobes: 0.48 Homozygous recessives, attached ear lobes: 0.18 What will be the allele frequencies for L and l in this generation? Did the frequency of the recessive allele (l), as compared to its frequency calculated in Part B, increase or decrease because of its deleterious effects on fitness? Does the possession of the recessive allele kill those who possess it? If those with attached ear lobes continue to be only half as successful in securing mates in each successive generation, what will happen to the frequency of the recessive allele in this population?Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. Researchers using genetic testing are able to determine the following numbers of individuals of each genotype in another population of geese: DD = 10576, Dd = 14503, dd = 4922. What is the actual frequency of genotype DD? A.) 0.483 B.) 0.164 C.) 0.352 D.) 0.734
- In corn, kernel color is governed by a dominant allele for white color (W) and by a recessive allele for yellow (w). A random sample of 152 kernels from a population that is in Hardy- Weinberg equilibrium reveals that 35 kernels are yellow and 117 kernels are white. What is the frequency of individuals with the homozygous dominant genotype?Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. Researchers using genetic testing are able to determine the following numbers of individuals of each genotype in another population of geese: DD = 10576, Dd = 14503, dd = 4922. -What is the actual frequency of genotype Dd? -According to the Hardy-Weinberg equilibrium, what is the expected frequency of genotype Dd, dd -According to the Hardy-Weinberg equilibrium, what is the expected number of individuals of genotype DD?Using the HardyWeinberg Law in Human Genetics In a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?
- In a population of 200 people, an allele F has a frequency of 84%. What is the frequency of allele f? Using the Hardy-Weinberg equation, estimate the numbers of homozygous dominant, heterozygous, and homozygous recessive genotypes. (Remember that the formula is: p2 + 2pq + q2 = 1, where p represents the dominant allele and q represents the recessive allele.) *Be sure to account for all 200 people in the population.The genetic composition of a population is 40 homozygous dominant (RR), 360 heterozygotes (Rr) and 600 homozygous recessive (rr). What is the observed frequency of the homozygous dominant individuals? [ Select] What is the observed frequency of the "r" allele? [ Select ] What is the expected frequency of the heterozygous genotype? [ Select ] If the Chi-squared value for this system is 2.40, is the population in Hardy-Weinberg equilibrium? Why? (note: the critical values for this test is 3.84), [Select ]Consider an autosomal locus with alleles A and a. If the the allele frequencies are as follows Freq(A) = 0.4, Freq(a) = 0.6. , then what is the predicted frequency of heterozygous Aa individuals, assuming the population is in Hardy-Weinberg equilibrium? Freq(Aa) = ? Enter a number between 0 and 1, inclusive, for example 0.33
- The UNF penguin lab decided to study the elusive polka dot penguin of Patagonia. They trapped a majority of the population using gummy worms as bait and collected the following information. Observed Genotype Frequencies (not in HWE) AA: 0.464 Aa: 0.427 aa: 0.109 If this population was in Hardy-Weinberg Equilibrium, what would be the expected genotype frequency for the heterozygotes? Retain 3 decimal places.This lab exercise requires that we count certain Mendelian traits among students present in the lab. Your professor will explain each trait being addressed and will then ask students to identify if they are dominant or recessive for that specific trait. The collected traits will then be plugged into the Hardy-Weinberg Equilibrium formula in order to calculate frequency of Homozygous dominant, Heterozygous and Homozygous recessive individuals in the same. p2 + 2pq + q2 = 100 given data: trait: hair swirl 19 individuals total. 10 had the homozygous dominant hair swirl trait: clockwise the nine other were recessive please do a step by step explanation with the calculation using this data, as I am very unfamiliar with what values mean what and the equation itself thank you!An allele of the G6PD gene acts in a recessive manner to cause sensitivity to fava beans, resulting in ahemolytic reaction (lysis of red blood cells) afteringestion of the beans. The same allele also confersdominant resistance to malaria. The heterozygote hasan advantage in a region where malaria is prevalent.Will the equilibrium frequency (qe) be the same foran African and a North American country? Whatfactors affect qe?
