You work for the science division of an agribusiness that is trying to stay ahead of upcoming food trends. The company predicts that duck eggs are likely to become a popular fad soon, and you've been tasked with determining the feasibility of harnessing the power of natural selection to breed ducks to produce more consistently sized eggs. You go through the recent records for the company poultry farm to examine egg size for ducks and their female offspring. The mean egg size is 120 grams, with a variance of 480 grams2. You plot out the results with the mothers' average egg size on the x-axis and average daughters' egg size on the y-axis, and you calculate the slope of your linear regression between the two as 0.28.What is the narrow-sense heritability for egg size in this population?
