Goals of Genetic Mapping:


1. Construction of high-density genetic map(s) using ESTs (transcribed DNA sequences) as markers.
In most cases ESTs are represented by functional genes.


2. Finding connection (association) between phenotype and genotype;
identification the actual genes involved in the trait (phenotype);
understanding the roles of those genes at the molecular level.

Finding association between phenotype and genotype usually done via QTL (Quantitative Trait Loci) mapping using high density molecular genetic maps.
