Assuming HardyWeinberg Equilibrium, what percentage of individuals in a population are carriers of TaySachs disease if p = 0.45? 


Two populations are completely isolated by a mountain range, but the environments on both sides of the range are exactly the same. Which of the following microevolutionary processes explains why the allele frequencies for the two populations would be different given enough time of isolation from each other? 


If the frequency of an Xlinked recessive disorder is 1 in 50 births, what is the frequency of affected males in the population? 



An evolutionary tree showing the relationships between past and present primates indicates which of the following? 



Which of the following most accurately defines what a gene pool is? 



Which of the following is an accurate statement about DNA profiling? 


1.
HardyWeinberg equilibrium:
p+ q=1
p2+2pq + q2 = 1.
Assumptions:
Answers: It can only be used when allele and genotype frequencies remain constant across generations in a population.
2.
Given:
P= 0.45
If the population is under HardyWeinberg equilibrium:
Thus, percentage of Tay Sach carriers population = 0.495 x 100 = 49.5
Answer: 49.5%

.1. The HardyWeinberg principle and its equations predict that frequencies of alleles and genotypes remain constant from generation to generation in populations that are not evolving. What five conditions does this prediction assume to be true about such a population? a._______ b._______ c._______ d._______ e._______ 2. Before beginning the activity, answer the following general HardyWeinberg problems for practice (assume that the population is at HardyWeinberg equilibrium).a. If the frequency of a recessive allele is 0.3, what is the frequency of the dominant...
2.3 Problem 3 The HardyWeinberg 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...
Question 1 Which of the following is NOT true regarding HardyWeinberg equilibrium (HWE)? Most real species will not be at HWE at all loci within their genome If a locus has genotype frequencies consistent with HWE, then the species as a whole is not evolving If a locus has genotype frequencies consistent with HWE, then no evolution is occurring at that locus If a locus does NOT have genotype frequencies consistent with HWE, then some form of evolution is occurring at that locus Question 2 Which of...
It is exceedingly rare for all the HardyWeinberg assumptions to be met in nature. Evolution is a change in allele frequencies in a population over time, so a population in HardyWeinberg equilibrium is not evolving. Match the following terms with the most correct statement. Each of these relates to evolutionary forces or conditions that violate the Hardy Weinberg assumptions. (Each term only matches to one statement). Genetic drift  Migration  Inbreeding  4 Mutation  Natural selection  Nonrandom mating a. Does...
reting Data: HardyWeinberg Equation 2 of 10 you use the Hardy Weinberg equation to answer questions about a hypotheticalcat population Part A A hypothetical population of 500 cats has two wees, Tandt for a gene that codes for tail length (Tis completely dominantot) The table below presents the phenotype of cats with each possible genotype, as well as the number of individuals in the population with each genotype. Assume that this population is in HardyWeinberg equilibrium Recall that the Hardy...
In a population of Mendel's garden peas, the frequency of the dominant A (purple flower) allele is 80%. Letp represent the frequency of the A allele and q represent the frequency of the a allele. Assuming that the population is in HardyWeinberg equilibrium, what are the genotype frequencies? A. 16% AA, 40 % Aa, 44 % aa B. 80% AA, 10 % Aa, 10 % aa C. 50 % AA , 25 % As , 25 % aa * E....
Why is it necessary for alleles to be combined randomly for the HardyWeinberg equation? O Random combinations of alleles produce genotype frequencies found in populations that are evolving. Pairing the alleles in this way produces the maximum number of heterozygotes in a population. The random pairing of alleles provides the evolutionary null hypothesis for a population. O Randomly pairing alleles provides evidence for the type of evolution a population has experienced.
1.)If the population frequencies of two alleles at a locus are B = 0.5 and b = 0.5, what is onepossible set of frequencies for the three resulting genotypes that would NOT reflect Hardy Weinberg equilibrium? 2.)In a population that is in HardyWeinberg equilibrium, the frequency of the homozygous recessive genotype is 0.09. What is the frequency of individuals that are homozygous for the dominant allele? 3.)In humans, Rhpositive individuals have the Rh antigen on their red blood cells, while...
1. Fixation of Dominant Alleles Start with a population that has a gene with two alleles (A and a) with classical Mendelian dominance that are at equal frequency (p0.5. q 0.5). Assume this first generation is at hardy Weinberg equilibrium. Calculate the genotype frequencies AA a. Aa b. Now assume some environmental change that makes the recessive phenotype completely unfit (fitness 0). Calculate the allele frequencies and genotype frequencies in the second generation. (Hint: Your calculations might be easier if...
 The HardyWeinberg equation does not really apply to populations like our genetics class. ey not? A The population is too small B) We have immigration C) The allele frequencies are changing rapidly due to mutation D) The genes are changing but not alleles E) There is strong selection on genes in our class
