Crossbreeding and choosing the best breed of cattle for each farm is important. Farmers should have goals and know what traits are most important for their farm to focus on. WebApplied the Breeder's equation to estimate the range of IQ for children, considering assumptions about the parents' and families' respective IQs. Regression to the mean is brutal, upper quartile never gets back to daddy's IQ if group mean is lower than his, which almost always will be if he is an outlier. R = h^2 S. R is the response to ...
