- . A farmer have 2000 cows. A total of 1500 of the cows are browh coated and the rest are white coated. Allele B for the brown coat is dominant, while allele b for the white coat is recessive: Assume that the population of the cows is at genetic equilibrium and bred randomly. Calculate the frequency for the dominant and recessive alleles of the population. i. Calculate the genotype frequencies in the F1 generation if the cows are left to breed randomly. ii. If the farmer adds another 1000 homozygous dominant brown cows into the populations, calculate the new dominant allele frequency. ii. iv. State three conditions for the Hardy Weinberg equilibrium to be achieved.In a population that meets Hardy-Weinberg equilibrium, the dominant allele frequency (A) is 0.7. What is the frequency of homozygous recessive individuals? Write how you reach answers in steps using the number provided. List all equations used. T T T F Paragraph := - E - Arial 3 (12pt) % D O Q e ES O f. * Mashups - 1 E E E - - H HTML CS5A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1A2 genotype, and 123 have the A2A2 genotype. What is the allele frequency of A1? Answer to 2 decimal places.
- 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?In a population that has been mating randomly for many generations, two 3. phenotypes are segregating; one is due to a dominant allele 6, the other to a recessive allele g. The frequencies of the dominant genotype is 0.7975. Estimate the frequency of: i. The recessive genotype i. The dominant and recessive alleles. ii. What is the frequency of the dominant phenotypes?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 ]
- 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.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?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.
- An autosomal locus has alleles A and a. The allele frequencies in a population at Hardy Weinberg equilibrium are p = Freq(A) = 0.1 q = Freq(a) = 0.9 What is frequency of heterozygotes in this population? Enter a single number between 0 and 1, for example 0.331) In cats, the allele for white fur(W) is completely dominant and will result in cats with all white fur in both the homozygous dominant and heterozygous cases. Suppose you look at 50 cats and notice that none of them are completely white. What's the allele frequency for the white fur allele in this population? 2) In carnations, the allele that makes red pigment (R) in flowers is incompletely dominant. Flowers that are red are homozygous dominant and those are pink are heterozygous. White flowers (r) are the result of the recessive allele. Suppose you look at a field of 100 carnations and notice 42 of the plants produce red flowers, 42 have pink flowers, and 16 produce white flowers. What's the allele frequency for both the red (R) and white (r) alleles?The frequency of the dominant allele “A” in an imaginary population is 0.20 (p) and the frequency of the recessive allele “a” in the population is 0.80 (q). What are the PREDICTED/EXPECTED genotype frequencies of all three genotypes (homozygous dominant, heterozygous, and homozygous recessive) if the population is in Hardy-Weinberg equilibrium?
