Which of the following are the assumptions of the HW equilibrium principle?
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene’s allele frequencies may change).
What does a one sample t test tell you?
The One Sample t Test examines whether the mean of a population is statistically different from a known or hypothesized value.
What is the difference between z-test and t-test?
T-test refers to a type of parametric test that is applied to identify, how the means of two sets of data differ from one another when variance is not given. Z-test implies a hypothesis test which ascertains if the means of two datasets are different from each other when variance is given.
Which of the following assumptions support Hardy-Weinberg equilibrium?
The five assumptions of Hardy-Weinberg equilibrium are a large population size, no natural selection, no mutation rate, no genetic drift, and random mating.
What are the factors affecting Hardy-Weinberg equilibrium?
The 5 factors are – gene flow, mutation, genetic drift, genetic recombination and natural selection.
How do you know if the t-test is significant?
If the computed t-score equals or exceeds the value of t indicated in the table, then the researcher can conclude that there is a statistically significant probability that the relationship between the two variables exists and is not due to chance, and reject the null hypothesis.
What are the 4 types of t tests?
Types of t-tests (with Solved Examples in R)
- One sample t-test.
- Independent two-sample t-test.
- Paired sample t-test.
What assumptions must be made in order for a model of the Hardy-Weinberg equilibrium to work?
What are the 5 factors that can change the allele frequency in a population?
Allele frequencies of a population can be changed by natural selection, gene flow, genetic drift, mutation and genetic recombination. They are referred to as forces of evolution.
Which of the following factors does not affect Hardy-Weinberg equilibrium?
It does not specifically selection for traits that are fit for the environment. Hence, answer is “Genetic drift”
