Suitable for English-speaking students

Objectives

Learning of the main topics of genetics including patterns of inheritance and mendelian analysis, chromosome theory of inheritance, molecular genetics, population genetics and quantitative genetics, with particular focus on the application of the genetic tools and theoretical concepts.

Learning outcomes and competences

General skills in the understanding of the different fields of genetics and their applications.

Working method

Presencial

Program

  1. Introduction to the course. Main objectives. Historical revision on the main concepts and theories of heredity.
2.Cellular reproduction. Cell division: the chromosome. Mitosis. Meiosis.

3.Mendelism:Mendel's experiments; Monohybrid and dihybrid crosses. Mendel’s principles:  dominant and recessive. Test cross. Reciprocal crosses.

4.Multiple alleles. Pedigrees analysis.

5.Gene interaction; changes in Mendelian ratios. Interaction between genes and alleles. Incomplete dominance, codominance. Multi-allelic systems. Pleiotropic genes; dominant and recessive epistasis. Regulatory genes. Penetrance and expressivity. 

6.Linkage. Recombination. Recombination fraction and distance between genes. Linkage maps.

7. Chromosomal theory of heredity. Characteristics related to sex. Deviations from Mendel's proportions. Autosomes and sex chromosomes. Sex determination.

8.Karyotype and chromosome structure. Cytogenetics thechniques. Chromosome mutations Structural and numerical chromosome changes. Types of changes in chromosomal structure. Changes in number; aberrant euploidy; monoploids and polyploids. Aneuploidy.

9. Some techniques used in breeding. Hybrid lines; production monoploidy; amphidiploid and production of new species in plants; aloploidy hybrids by somatic hybridization. 


10.Population genetics. Genetic polymorphism and gene frequencies. The Hardy-Weinberg equilibrium. Changes in allelic frequencies: genetic drift, mutation, migration and selection. Inbreeding and assortative mating. 

11. Molecular markers. Detection methods of genetic variability; types and use of molecular markers.
