BIOL 2081C Lecture Notes - Lecture 33: Standard Deviation, Heritability
Document Summary
Learning objectives: **all answers in lecture 33 & 34 notes*: define a complex trait, and distinguish between continuous (quantitative), dichotomous (aka simple inheritance, or single-gene inheritance), and threshold traits. **refer to lecture 33 notes: interpret experiments to determine the relative influences of genes and the environment on a given phenotype, a. Among sources of phenotypic variation of a complex trait, distinguish between variation due to genotype, environment, genotype by environment interaction, and genotype by environment association. Given statistical data on variance, calculate the contribution of genetics and environment. Lecture 33 and lecture 34 notes: define and calculate broad-sense-heritability. Pre-class assignment: complete lo1, define the following terms: broad-sense heritability, narrow-sense heritability. **refer to lecture 34 notes: statistics are essential to analyzing complex traits, so make sure you know the basics of the normal distribution, including the mean, standard deviation, and variance.
