Problem 1: In your own words (not from Google or the slides), describe narrow-sense heritability (1 pt, 1 sentence).
Problem 2: Why is narrow-sense heritability (the slope) unlikely to be equal to 1? (1 pt, 1-2 sentences)
Problem 3: For three of the five TRAITS (IE: height is one trait, use all trait graphs) below do the following:
A. Specify the trait type (morphological, physiological or behavioral). (0.5 pts for each trait)
B. What are possible environmental factors that could affect these traits? (0.5 pts for each trait, 1 sentence per trait)
Problem 4: Using the provided figures below (pages 2-5), interpret the results for each of the three traits you specified in question #3 (what was the trend, if any, in the data; what was the estimated narrow sense-heritability; how strong is the relationship? Do not regurgitate suggested cutoffs and consider R2 in your response. (I.E: Do NOT say "The heritability is decent because it is 0.5") (1 pt for each trait, 1-2 sentences for each trait)
Problem 5: How could measurement error have influenced the results (provide hypothetical examples for each trait you mention)? (1 pt per trait, 1-2 sentences)
Problem 6: Provide one possible reason why the R2 is low for some of these traits? (1 pt, 1-2 sentence).
Problem 7: In this data set, ~80 female students and ~40 male students responded to the questionnaire. How do you think the results on Son-Midparent height may have been different if there had been 80 male students? (1 pt, 1-2 sentences)
Problem 8: Based on these results and the lectures and reading, what kinds of traits (physiological, morphological, behavioral) generally have the highest heritability in humans and why?
