This teaching activity contributes to the achievement of the Sustainable Development Goals of the UN 2030 Agenda.
Academic Year 2021/2022
Learning outcomes
At the end of the course, the student possesses knowledge about the basic mechanisms of transmission of genetic information, the preservation of its stability and the origin of variability. In particular, the student is able to use a specific scientific language and the most important methodological tools for the analysis of genetic variability.
Course contents
Introduction to genetics. The structure of DNA, DNA replication. Gene, allele, genotype, phenotyope definition. Relation between genes and traits; gene expression.
Mendelian genetics, monohybrid crosses, dihybrid crosses (independent assortment), probability and Chi-Square. Mitosis and meiosis, chromosomal basis of inheritance, sex determination and sex-linked characteristics, dosage compensation in mammals. Human pedigree analysis.
Extensions of mendelian genetic analysis, multiple alleles, lethal alleles, types of dominance, penetrance, gene interactions and epistasis, Maternal effect, interaction of genes and environment.
Non-mendelian inheritance: mitochondria and chloroplasts.
Linked genes, recombination, constructing genetic maps with recombination frequencies.
Bacterial and viral genetics.
Genetic variability. Molecular basis of mutations. Point mutations and their consequences. Chromosomal mutations. Transposable elements.
Recombinant DNA technology: OGM, CRISPR Cas system
Population genetics: allele frequencies; Hardy-Weinberg equilibrium, Mutation and selection, genetic drift, migration.
