Lecture 1: Mutations and Disease
Describe the genetic mutation responsible for citrullinemia in cattle. How does this mutation affect the animal's physiology, and why do only homozygous recessive individuals show symptoms?
Explain the concept of incomplete dominance and provide an example from animal genetics where this type of gene action is observed.
What is myostatin deficiency, and why does it cause health problems in animals such as Belgian Blue cattle? Discuss the advantages and disadvantages of this mutation in agricultural contexts.
How can healthy parents produce offspring with a genetic disorder like citrullinemia? Use Mendelian inheritance to explain this phenomenon.
Compare and contrast recessive and dominant inheritance patterns in genetic disorders. Why is it easier to eliminate a dominant allele causing disease from a population than a recessive one?
Lecture 2: Genome Technologies
Explain the key differences between first, second, and third-generation sequencing technologies. Why might a researcher choose one method over another depending on the application?
What challenges do repetitive DNA sequences pose during genome assembly, and how can these be resolved using third-generation technologies?
Describe the process of genome annotation and its importance in veterinary research. How does the use of mRNA sequencing contribute to identifying functional genes in a genome?
How has the cost and time required to sequence genomes changed from 2000 to the present, and what impact has this had on veterinary science?
Why is genome sequencing important for understanding disease biology and developing treatments in veterinary medicine? Provide an example.
Lecture 3: Animal Breeding
Explain the concept of polygenic inheritance and provide an example relevant to animal breeding.
What does heritability (h²) measure, and why is it important in selective breeding programs?
Using the breeder’s equation ( R = h² \ S), explain how selection in animal breeding leads to changes in a population's trait over generations.
Describe how genome-wide association studies (GWAS) are used to identify genetic variants associated with complex traits in animals.
Compare traditional progeny testing with genomic selection in livestock breeding. What are the advantages of genomic selection?
Lecture 4: Animal Breeding II, Companion Animals, Wildlife
What is pleiotropy and how can it affect breeding decisions in companion animals? Provide an example.
Explain the concept of genetic correlations and their importance in animal breeding. How can they be used to improve traits?
Discuss the unintended consequences of intense selection for breed standards in dogs. What are some health issues related to these practices?
What role does genomic data play in wildlife conservation? Give an example of how it can be used in captive breeding programs.
How does linkage disequilibrium influence the selection of traits in animal breeding?
Lecture 5: Molecular Diagnostics
Explain the significance of PCR in veterinary molecular diagnostics.
Describe the role of primer design in ensuring the specificity of PCR results. Why are melting temperatures crucial?
What are some limitations of PCR, and how might these impact its accuracy in diagnostic applications?
Discuss how DNA metabarcoding could be applied in a veterinary context. Provide an example.
Compare PCR and isothermal amplification. In what situations might you prefer one technique over the other?
