If I were looking to cull a dairy cow, I would look at expected progeny difference, not most probable producing ability. T/F . Know about correlations and how to ID them by looking at graphs. . Understand what the slope of a line representing the graphing of two values against each other means as far as regression/regression equations and correlations of traits be able to discuss. View video in D2L PPT about test grades and hours studying as an example. . Be able to calculate means and standard deviations like the video in the D2L PPT we discussed in class. . Be able to discuss what means plus or minus the standard deviation means; be able to calculate the standard deviation from the variance. . What is the fastest way to find out if an animal is a carrier of a simply-inherited trait exhibiting dominance such as horn status, black/red coat color, scrapie, callipyge, marble bone, PSS and more? . Be able to calculate EBVs from EPDs and vice versa (EPD=1/2 of the EBV), also predict offspring performance with sire and dam EPDs and the average performance for the population
