This is Problem 1C. Use your scratch paper to show your work (points will be deducted if no work is shown, even if the final number is correct). Enter the final number for this question online before you move to the next question. You will upload all your papers at the end of the exam. Using all the information in Problem 1A, predict the WW for an animal with a 62 lb BW.  

Heterosis is greater for lowly heritable traits

Heterosis is greater for more similar breeds

This is Problem 7A. Use your scratch paper to show your work (points will be deducted if no work is shown, even if the final number is correct). Enter the final number for this question online before you move to the next question. You will upload all your papers at the end of the exam. In a population of captive animals, you have capacity to hold 50 animals. For this species, the best reproductive rates are achieved with a ratio of four females mated to each male. If you follow that ratio, what is the effective population size?

Assume straightbred Herefords average 450 lb at weaning and straightbred Simmentals average 500 lb. If heterosis for this trait is 0.06, how much do you predict the crossbred calves will weight?

Please scan all your scratch paper (all 10 – each side of the 5 sheets you started with, including the ones you did not use). You can use a scanner app on your phone or a scanner if you have it next to you. All sheets need to be scanned as one file (not 10 individual files) – this question will only allow you to upload one file. Send the file to your email (or desktop if you have that capability), access your email on the computer, download the file to your desktop, and then upload that file in this question.

Enter the final number for this question online before you move to the next question. You will upload all your papers at the end of the exam. Consider an 8 breed rotational crossbreeding system where the following breeds are introduced in this order: A, B, C, D, E, F, G, H. Calculate the percentage of breed G in your population at equilibrium.
