Catalog Description:

This course combines the study of basic genetic principles with the study of the anatomical and physiological aspects of reproduction as they relate to equine reproduction. Genetic principles to be emphasized include basic inheritance, selection techniques, mating systems, heterosis, and performance evaluation. Reproductive aspects to include endocrinology, estrous cycles, mating behaviors, gametogenesis, conception, gestation, parturition, and maternal behaviors. Artificial insemination, embryo manipulation, and current innovations in productive biotechnology will also be examined.

COURSE CONTENT

Outcomes and Objectives:
At the conclusion of this course, the student should be able to:

The student will:

1. Examine concepts of gene frequency, alleles, homozygosity,

   heterozygosity, dominance, co-dominance, and recessive genes.

2. Compare and contrast artificial and natural mating and selection

   systems.

3. Compile the possible genetic and phenotype ratios for two traits,

   resulting from the mating of two heterozygous individuals, by using

   the Punnet Square method.

4. Describe the effect of heritability on selection progress for

   individual traits.

5. Interpret EPD's, ratios, breeding values, and indexes for use in sire

   selection.

6. Critique the mating concepts of inbreeding, linebreeding, outcrossing,

   and crossbreeding.

7. Describe the physiological functions of the major anatomical points of

   the male and female reproductive tracts.

8. List the origin and function of the major hormones, both male and

   female, involved in reproduction.

9. Describe the physical and behavioral expressions of estrus.

10. Appraise the anatomical and physiological aspects of conception,

   implantation, and gestation.

11. Critique various methods of pregnancy detection.

12. Describe the correct fetal position, delivery process, approximate

   timeline and maternal behaviors for a normal parturition.

13. Identify factors that may contribute to dystocia.

14. Explain the advantages and limitations of artificial insemination.

15. Analyze the significance and benefits of innovations in reproductive

   biotechnology, such as cloning and the splitting, sexing, storing and

   transfer of embryos.
