Learning outcomes Details

Students who successfully complete this course should be able to:

  1. Apply Mendel's principles of inheritance and discuss the importance of these and their exceptions in breeding programmes, particularly with respect to lethal and detrimental genes and changing gene frequencies.
  2. Apply complex principles of inheritance to breeding schemes, including heritability, genetic variation, breeding values and selection indices as well as identify the impact of reproductive technologies on genetic gain.
  3. Predict an animal's breeding values based on own, pedigree or progeny records.
  4. Calculate and interpret genetic relationships, inbreeding, crossbreeding, mating plans and maternal effects.
  5. Describe the structure of the main livestock industries and identify the strengths and weaknesses of the structures with respect to genetic gain.

Please note: Learning Outcomes are subject to change until the beginning of the semester in which the course is delivered.
