What is not Hardy-Weinberg equilibrium?
If the allele frequencies after one round of random mating change at all from the original frequencies, the population is not in Hardy-Weinberg equilibrium and evolution has occurred within the population.
What are the 4 conditions of Hardy-Weinberg equilibrium?
The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection.
What are the 5 parts of the Hardy-Weinberg principle?
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) …
Which of the following is not a requirement for Hardy-Weinberg equilibrium?
Hardy-Weinberg requires no migration, random mating, large population size, no natural selection, and no mutation.
What kind of equilibrium is Hardy-Weinberg equilibrium?
Please review Figure 7.30 on page 246. The question did not state that the population is in Hardy-Weinberg Equilibrium, so you should estimate the allele frequency as: Frequency F = [(66)/(66 + 103 + 74)] + 0.5*[(103)/(66 + 103 + 74)]) = 0.484. Please review pages 222 – 223.
Which of the following defines Hardy-Weinberg equilibrium?
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
Which condition is not required for a population to be at Hardy-Weinberg equilibrium quizlet?
very large population (genetic drift doesn’t occur), no emigration or immigration, no mutations, random mating, no natural selection.
What are the conditions that must be met for genetic equilibrium?
The Hardy-Weinberg model states that a population will remain at genetic equilibrium as long as five conditions are met: (1) No change in the DNA sequence, (2) No migration, (3) A very large population size, (4) Random mating, and (5) No natural selection.
What are the five evolutionary mechanisms give a brief description of each?
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).
What causes deviation from Hardy-Weinberg equilibrium?
Small Population Sizes: Genetic Drift
In a small population, the sampling of gametes and fertilization to create zygotes causes random error in allele frequencies. This results in a deviation from the Hardy-Weinberg Equilibrium. This deviation is larger at small sample sizes and smaller at large sample sizes.
What are the five evolutionary mechanisms?
They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.
