Course: Equine Science (18104-18) > Section: Understanding Equine Genetics and Reproduction

Explanation should include

- explanation of the differences between DNA and ribonucleic acid (RNA), as well as between gene, allele, and chromosome
- description of how genetics determines coat color
- differences between phenotypic and genotypic traits
- the relationship between dominant and recessive traits
- the differences between heterozygous and homozygous
- genetic abnormalities
- use of the sum rule to calculate the probabilities of offspring with dominant and recessive phenotypes
- use of the product rule to predict frequencies of fertilization events.
