Make scatter diagram of points showing the relationship between Avg Height of Parents (x-axis) and Male Offspring Height (y-axis). A positive slope would suggest a positive correlation of these measures. Give a quantitative genetic explanation for the correlation (i.e. what does the result indicate about the genetic variance and heritability of the trait in the population?).
Homework Answers
Heritability (H2) measures what fraction of variation in a trait is due to variation in genes and what fraction is due to variation in environment. Its value ranges from 0 (no correlation) to 1 (perfect correlation).
Correlation between average height of parents and male offspring height was found to be nearly 1.
Thus, there is a positive correlation between average height of parents and male offspring height and variation in the trait is due to genetic variance. Environment has little or no effect on the height of male offspring.
