I identified several QTLs using several types of markers. Now I would like to build a genetic map with 2 or 3 types of molecular markers and I need to showed these QTLs (positions) and these identified by other studies (gramene) on this map.
You can easily combine different markers like SNPs and SSRs by analyzing each single marker-allel in a dominant manner (1=present, 0=absent); give each single SSR-allel or SNP-allel a different name (SSR1a, SSR1b). In Joinmap you later can combine the single marker alleles to identify the homolog chromosomes.
