b. A population that receives new individuals from a normally distant population.
c. q + p = 1
d. A population in which the allele frequencies do not change over time
There are five conditions that must be met for a population to be in Hardy-Weinberg equilibrium. Which of the following is not one of those conditions?
Group of answer choices
non-random mating
no migration
no natural selection
no mutation
large population size
Five conditions are required to maintain the Hardy–Weinberg equilibrium in a population.
Closed population
Large population
Random mating
No net mutations
No natural selection
If any of these conditions is not being met, the allele frequencies in the population will change, leading to microevolution in the population.Match each of the following scenarios to the Hardy–Weinberg condition that is NOT being met:An increase in antibiotic resistance among bacteria exposed to antibiotics occurs. AnswerCaribou from one herd move to a new area and breed with caribou of a completely different herd. Answer Among eastern bluebirds, more brightly coloured males breed with more brightly coloured females. AnswerDue to overhunting, there is little genetic diversity in the current population of bearded vultures, which have all descended from a population of only 36 birds. Answer

- which of the following would be sufficent for the hardy-weinberg equations to accurately predict geontype frequencies from allele frequenceies. - p+q = 1 - the population is not evolving due to natural selection -the population is not evolving due to any of the conditions that disrupt hardy-weingberg - the population is infinetely largearrow_forwardWhich of the following is likely to be observed if there has been a strong positive selection on a particular genetic locus within a population? Group of answer choices There will be a lot of variation in DNA surrounding the genetic locus in question within the population. There will very little variation in DNA surrounding the genetic locus in question within the population. You will see very low frequencies of the genetic locus in questionarrow_forwardThe Hardy–Weinberg principle states that allele and genotype frequencies remain constant from one generation to the next, as long as specific conditions are met.Choose Yes or No for the conditions that must be met from the provided statements below. Mutations are exponentially occurring. All members of the population breed. Everyone produces the same number of offspring. The population is infinitely large. There is no migration in or out of the population. No net mutations are occurring. Natural selection of beneficial traits is occurring. Natural selection is not occurring. All mating is completely random. Offspring are able to migrate out of the population.arrow_forward
- If gene A/a is not in Hardy-Weinberg equilibrium due to natural selection such that individuals with the genotype AA have a fitness value of 1.0, heterozygotes have only slightly reduced fitness at 0.9, and individuals with the genotype aa have a fitness value of 0.6, what kind of change in allele frequency would you expect to see over time assuming you start with equal frequencies of the 2 alleles?arrow_forwardGodfrey Hardy and Wilhelm Weinberg stated the principle of equilibrium to describe the genetic makeup of a population. The theory, also known as the Hardy-Weinberg principle of equilibrium, states that a population’s allele and genotype frequencies are inherently stable. Which of the following phenomena could disrupt this equilibrium? Mutations Selection pressure Migration All of the given choicesarrow_forwardA recessive lethal allele has achieved a frequency of 0.22 due to genetic drift in a very small population. Based on natural selection, how would you expect the allele frequencies to change in the next three generations? Now: Your calculation can assume that genetic drift is not altering allele frequencies in either direction.arrow_forward
- In a population experiencing no selection, genetic drift, gene flow, mutation or non random mating, the allele frequencies at a locus where the R allele is dominant over the r allele, are as follows. R= 0.3 r=0.7 What is the expected heterozygosity of the population at that locus?arrow_forwardYou survey a population of minnows in Hardy-Weinberg equilibrium and find that there are three different genotypes; Red, Purple, and Blue fins. The genotypes for Red (RR), Purple (Rr), and Blue (rr) fins have different survival rates at 0.7, 0.8, and 0.5, respectively. The size of the population does not decrease from generation to generation and all individuals lost to selection are replaced by new individuals being born. If the population starts with 30 Red, 30 Purple, and 40 Blue fins, what is the expected number of individuals of each genotype in the next generation (round to nearest whole individual)? csn you clearly show each step of the work.arrow_forwardIn monkeys, black coat color (B) is dominant over brown color (b). A population of monkeys was found to be composed of 67 brown coated individuals and 119 black coated individuals. What is the frequency of the b allele in this population? What is the frequency of the B allele in this population? Based upon the Hardy‑Weinberg formula, what proportion of the population is expected to have the genotype BB? Based upon the Hardy‑Weinberg formula, what proportion of the population is expected to bave black coat color? Based upon the Hardy‑Weinberg formula, how many individuals in this population would be expected to have the genotype Bb?arrow_forward
