The Hardy–Weinberg principle relies on a number of assumptions: (1) random mating (i.e, population structure is absent and matings occur in proportion to genotype frequencies), (2) the absence of natural selection, (3) a very large population size (i.e., genetic drift is negligible), (4) no gene flow or migration, (5) …
What are the five assumptions of Hardy equilibrium?
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.
What are the assumptions of Hardy-Weinberg equilibrium quizlet?
What are the assumptions of Hardy-Weinberg Equilibrium? large populations, no genetic drift, no natural selection/mutation or migration, no assortative mating /sexual selection or inbreeding.
What are the five conditions for Hardy-Weinberg equilibrium quizlet?
Terms in this set (5)

- No gene flow (emigration, immigration, transfer of pollen, etc)
What is Hardy-Weinberg equilibrium What does it assume?
The Hardy-Weinberg principle assumes that every individual in a population has an equal chance of mating with every other individual, totally random mating. In a population at Hardy-Weinberg equilibrium, nobody gets to be picky. Random mating, also known as a panmictic population, almost never happens in real life.
What are the five evolutionary mechanisms?
There are five key mechanisms that cause a population, a group of interacting organisms of a single species, to exhibit a change in allele frequency from one generation to the next. These are evolution by: mutation, genetic drift, gene flow, non-random mating, and natural selection (previously discussed here).
Which of the following is an assumption of the Hardy-Weinberg model quizlet?
The Hardy-Weinberg model makes the following assumptions: no selection at the gene in question; no genetic drift; no gene flow; no mutation; random mating.
Why is the concept of Hardy Weinberg equilibrium useful for evaluating natural selection?
The Hardy-Weinberg Theorem demonstrates that Mendelian loci segregating for multiple alleles in diploid populations will retain predictable levels of genetic variation in the absence of forces that change allele frequencies.
What is another name for the evolutionary force called gene flow?
gene flow, also called gene migration, the introduction of genetic material (by interbreeding) from one population of a species to another, thereby changing the composition of the gene pool of the receiving population.
What is the physical location of a gene within the genome called?
Locus. = A locus is the specific physical location of a gene or other DNA sequence on a chromosome, like a genetic street address. The plural of locus is “loci”.
Which is not a condition for Hardy-Weinberg equilibrium quizlet?
Which of the following is NOT a condition of the Hardy-Weinberg equilibrium? Mutations cannot occur in a population. Mating within a population must be random.
What is one condition that must be met for a population to be in genetic equilibrium quizlet?
What is one condition that must be met for a population to be in genetic equilibrium? There is no genetic drift. A population has a small size, high level of genetic drift, and very little migration into the population.
How does gene flow affect biodiversity?
Gene flow is an important mechanism for transferring genetic diversity among populations. Migrants change the distribution of genetic diversity among populations, by modifying allele frequencies (the proportion of members carrying a particular variant of a gene).
