Class Objectives
/Class Outline
This course will provide an overview of animal breeding with relation to animal genetics and statistics, focusing on the genetic dominance of and evaluation methods for characteristics that can be the objects of breeding. Furthermore, the course will provide an overview of new and developing breeding methods using DNA markers.

Suggestions on
Preparation and
Grading Method Evaluation is based entirely on the score of the end-of-semester examination. However, as per university rules, students whose unexcused absences equal one third or more of the total number of classes will not be permitted to take the final examination.
