A dairy producer has estimated the following variance components for daily milk production, which is a repeated trait. O'BV = 32 1b2 o' GCV = 12 1b2 O'ED = 16 1b- O'Et = 15 1b2 Calculate the narrow-sense heritability for this trait. Question 31 5 pt A dairy producer has estimated the following variance components for daily milk production, which is a repeated trait. O'BV = 32 1b2 O'Gov = 12 lb2 O'EP = 16 1b2 O'Et = 15 1b2 Calculate the repeatability for this trait.Below are the data from a very small sampling of pigs. Phenotypic values are given for days to 230lb (D230) and Backfat thickness (BF). Some of the sample statistics are also given. Days to 230 (D230) Backfat (BF) 173.6 days 1.12 inches 91.3 days? 0.102 inches' 9.56 days 0.32 inches Cov(D230, BF) = -2.17 days.inches Calculate the regression coefficient for a regression of Backfat on Days to 230lb. Make sure to include the appropriate sign in your answer. Question 29 5 pts Below are the sample statistics from a small sampling of pigs. (NOTE: these statistics are slightly. different than in previous questions). Days to 230 (D230) Backfat (BF) 186 days 0.95 inches 68.4 days 0.076 inches 8.27 days 0.28 inches Cov(D230, BF) = -1.96 days.inches brzan.BF = -25.79 days/in bar-D23D = -0.029 in/day Use this info to predict the amount of Backfat that would be expected for a pig that took 181 days to get to 230lbs
