- What is population genetics?arrow_forwardIn a population, the dominant phenotype of a certain trait occurs 91% of the time. What is the frequency of the dominant allele?arrow_forwardWhich type of selection (directional, disruptive, stabilizing) changes the overall average phenotype in a population? How does it do this? What does "additive” mean? Why aren't dominant and epistatic variances considered to be additive?arrow_forward
- In a system that meets the requirements for Hardy-Weinberg equilibrium 25% of individuals exhibit the recessive phenotype for a trait.

- What impact do cases a multiple alleles have on the number of kinds of phenotypes displayed in the population?arrow_forwardWhich of the following statements about quantitative genetics is TRUE? Heritability is the measure of the proportion of an individual's phenotype that is due to genetics. QTL mapping provides an overestimate of the number of genes contributing to a quantitative trait. A threshold trait is measured in whole numbers. An H2 value (broad-sense heritability) that approaches 0.0 means that almost all the phenotypic variation is determined by genetic differences. The h2 (narrow-sense heritability) value is a prediction of the impact that selection may have in altering an initial population by artificial selection.arrow_forwardWhat is the purpose of a confidence interval in statistics? a) To estimate the range within which a population parameter lies b) To test the difference between two sample means c) To measure the central tendency of a data set d) To compare the variances of two samplesarrow_forward
