- Describe how genetic influences of quantitative traits can be studied in humans. Describe some of the types of studies and why they are helpful. Answer in at least 4 full sentences.For each of the following traits, select whether it is a continuous trait or a discrete trait in humans. Trait Discrete trait / Continuous trait Height Answer Albinism Answer Learning ability Answer Body weight Answer Number of fingers AnswerThe following table gives the percentage of twin pairs studied in which both twins expressed the same phenotype for a trait (concordance). Percentages listed are for concordance for each trait in monozygotic (MZ) and dizygotic (DZ) twins. Assuming that both twins in each pair were raised together in the same environment, what do you conclude about the relative importance of genetic versus environmental factors for each trait?

- QTL mapping and GWA (association) mapping are two different methods used to identify genes that affect complex traits. For each of the following statements, choosewhether it applies to QTL mapping, association mapping, or both.whether it applies to QTL mapping, association mapping, or both.Which 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.The effects of poverty, stress, racism, or socioeconomic status have not been conflated with the effects of genetics or ancestry. True False
