Module aim (aims)

This course will place special emphasis on heredity and variation, the mechanisms governing genetic inheritance, Mendelian and non-Mendelian genetic analysis and application of knowledge and skills in practical activities.

Pre-requisites in terms of knowledge, skills and social competences (where relevant)

Basic knowledge of cell biology and genetics, group work skills.


Week 1: Introductory lecture: laws of inheritance, non-Mendelian inheritance, allelic and non-allelic interactions.Week 2: Lecture: Sex-linked inheritance: sex–linked traits and sex- influenced traits, mechanism of sexdetermination.Week 3: Lecture: Mutations – classification, mechanisms of spontaneous and induced mutations, repair, role in genetic analysis and evolution.Week 4: Lecture: Cytoplasmic inheritance – basis and mechanism, role of organellar genes.Week 5: Lecture: Quantitative inheritance – concept, genes and environment - heritability, penetrance and expressivity.Week 6: Seminar: Deviations from the Mendelian inheritance: types of dominance, lethal alleles, complementation, epistasis – presentation and discussion.Week 7: Seminar: Sex determination in plants, animals and human - presentation and discussion.Week 8: Seminar: Drosophila melanogaster as a model organism for genetic analysis and for human genetic disorders (e.g. Parkinson’s, Huntington’s, Alzheimer’s diseases etc.) – presentation and discussion on the selected papers.Week 9: Seminar: Genetic experimental design: planning, data generation, data analysis, preparing final report.Week 10: Laboratories: Basics of setting up Drosophila crosses experiment: breeding conditions, life cycle, gender recognition, types of mutants.Week 11: Laboratories: Dihibrid crosses experiment on a Drosophila and maize models.Week 12: Laboratories: Inheritance of sex-linked traits – Drosophila crosses experiment.Week 13: Laboratories: Gene complementation - Drosophila crosses experiment.Week 14: Laboratories: Cytological preparation of polytene chromosome in larval stages of Drosophila.Week 15: Seminar: module summary, presentation of experiment reports.
