Genetic association studies


Understand the need of preserving the genetic variability  To know the objectives of germplasm banks Understand basic population genetic concepts to measure genetic diversity  Be familiar with multivariate methods to classify genotypes using molecular markers Reinforce Quantitative Genetics theory  Understand the basis of Quantitative Trait Locus (QTL) analysis To know the most common QTL mapping methods To provide a general view of the answers obtained by QTL analysis experiments. To introduce the advance backcross-QTL strategy to introgress genetic variability from wild species into elite germplasm.  To give a view of the future applications of Quantitative Genetics and QTL analysis in Genomics research.  


Basic statistics (means, ANOVA, regression)            
 Genetics (DNA, chromosome, gene, Mendel law, locus, alleles, heterozygosity)

Content Delivery

- The main material will be powerpoint presentations - For each subject, the next sequence will be followed             1- A brief introduction to remind or strength the basic concepts/methologies needed to understand the subject             2- Explanation of the statistical/genetic theory             3- Case studies to apply the methodology             4- Focus on the interpretation of the results             5- Computer practice  

Coursework And Assignment Details

·         Written exam with three types of questions 1- Multiple choices. The student will have to choose the right answer from 4 different options. Every right choice will sum 1 point. These questions will represent 65% of total grade. 2- Short questions. The student will have to define with his own words some of the concepts explained during the course. Each question will sum up to 2 points. These questions will represent 15% of total grade. 3- Problems. The student will have to analyze some data and interpret the results. Each question will sum up to 4 points. These questions will represent 25% of total grade.
