Homework 3 Due: June 9, 2025 @ 10pm 30 points 1. If your neighbor told you his calves this year had a phenotypic variance for yearling weight of 100 lb and with research, you found that the genetic standard deviation of weaning weight is typically around 29 lb. a. What would the heritability of weaning weight be in that herd? (5 points) b. Another neighbor stopped by while you were going through this discussion and didn't understand what heritability was. How would you explain that to the neighbor (assume that neighbor had a high school education)? (5 points) Given the following animals and their respective breeding values for the direct and maternal components of weaning weight (show your math for partial credit) a. Rank the bulls based on order of preference (1 to 5; with 1 being your first choice) for producing progeny for sale at weaning on a weight basis? (5 points) b. Which bull would you choose to produce replacement females for your herd assuming you would be selling the heifers' offspring at weaning on a weight basis with heavier being better? Rank all of the bulls for this selection criterion. (6 points) ate w aCe b. Which bull would you choose to produce replacement temales tor your herd assuming you would be selling the heifers' offspring at weaning on a weight basis with heavier being better? Rank all of the bulls for this selection criterion. (6 points) Bulls BVb BVm Macho 6 16 Paco 9 10 Romeo 20 -5 Ceasar 8 20 Napoleon 25 -10 3. The repeatability of mature weight in beef cattle is .65. If the phenotypic variance for mature weight in your herd was 14,400 Lb?, What percentage of the differences in mature weight would be due to a. b. differences in producing ability? (3 points) What percentage would be due to differences in temporary environmental effects? (3 points) What is the standard deviation in producing ability? (3 points)
