a. Which of the following two large populations is in Hardy-Weinberg Equilibrium with respect to the A locus? Genotype frequencies AA Aa aa Population I .430 .481 .089 Population II .640 .320 .040 b. What are the expected equilibrium frequencies for the population that is not in equilibrium? c. How long will it take for the non-equilibrium population to reach equilibrium under conditions of random mating and assuming no selection at this locus?
Ans- c) Depending on whether the organism is a 'true' tetraploid or an amphidiploid will determine how long it will take for the population to reach Hardy–Weinberg equilibrium.

It is exceedingly rare for all the Hardy-Weinberg assumptions to be met in nature. Evolution is a change in allele frequencies in a population over time, so a population in Hardy-Weinberg 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...
please click on the photo to see all of it The basic equations of Hardy-Weinberg Equilibrium p² + 2pq + q2 = 1 p+q=1 p= frequency of the dominant allele in the population 9 = frequency of the recessive allele in the population př= percentage of homozygous dominant individuals q* = percentage of homozygous recessive individuals 2pq - percentage of heterozygous individuals 1. You have sampled a population in which you know that the percentage of the homozygous recessive genotype...
Question 1 Which of the following is NOT true regarding Hardy-Weinberg 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...
Assume Hardy-Weinberg equilibrium. In a population with 1000 individuals, if genotype frequencies are equal to AA 50%, Aa 42%, and aa 8%, what is the probability of obtaining a "AA" Zygote? 7% 50% 71% 5%
.1. The Hardy-Weinberg 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 Hardy-Weinberg problems for practice (assume that the population is at Hardy-Weinberg equilibrium).a. If the frequency of a recessive allele is 0.3, what is the frequency of the dominant...
Suppose a population of organisms is in Hardy–Weinberg equilibrium with respect to a gene that has two alleles, Y and y. The YY genotype has a frequency of 0.11, the Yy genotype has a frequency of 0.44, and the yy genotype has a frequency of 0.45. Calculate the frequency of each allele to two decimal places. Y allele frequency: y allele frequency:
In a population of wild sweet pea plants that you assume are in Hardy-Weinberg equilibrium, 1% of plants express a recessive white flower color. A) What is the expected frequency of heterozygotes in the population? Number You have noticed a shift in pollinator frequency and you want to test whether this has resulted in selection on flower color. You sample 1000 plants and genotype them at this locus. B) How many of each genotype do you expect based on the...
Which of the following statements regarding the Hardy-Weinberg Equation is TRUE? Answers: It can only be used when allele and genotype frequencies remain constant across generations in a population It can only be used when allele and genotype frequencies change across generations in a population It has no assumptions It mathematically shows how recessive alleles in a population decrease over time It reveals when allele frequencies change over time in a population Assuming Hardy-Weinberg Equilibrium, what percentage of individuals in...
because real life populations, are, of course, not infinetly large, why is the hardy-weinberg condition of an infinitely large popualtion usually met for natural population? none drift naturally happens in every population most natural popualtions are large enough that chance favtors have negligible effects on allelic frequencies most population are anyway not following any of the 5 assumptions
