ANS 3384 FINAL EXAM STUDY SHEET 1. Horse Color Genetics: Be able to work a problem involving the bay, sorrel, black, buckskin and palomino colorations and the tobiano, overo (homozygous lethal) and roan (lethal) spotting patterns. 2. Detecting sires for the presence of recessive genetic defects. Be able to explain how to use recessive females, known carrier females and daughters of a bull to detect whether or not the male carries a genetic defect. Know how many offspring would be required to test the bull at the .01 level of possible error. Understand how daughters of a known carrier could also be used and know the advantages and disadvantages of all systems of detection. Remember some of the genetic defects that have been important in recent years such as HYPP, HERDA and CID in horses and BLAD and CVM in Holsteins and how each is being dealt with by breeders through the use of DNA probes. (Understand how the use of DNA testing can be used to detect heterozygous individuals and examples of specific defective genes that can be detected in this fashion.) 3. Be able to explain how to incorporate a dominant gene into a population without it through a process of upgrading with selection. 4.
