Integrating the markers Pan I and haemoglobin with the genetic linkage map of Atlantic cod (Gadus morhua).

ABSTRACT:

Background

Haemoglobin (Hb) and pantophysin (Pan I) markers have been used intensively in population studies of Atlantic cod (Gadus morhua) and in the analysis of traits such as temperature tolerance, growth characteristics and sexual maturation. We used an Illumina GoldenGate panel and the KASPar SNP genotyping system to analyse SNPs in three Atlantic cod families, one of which was polymorphic at the Hb β1 locus, and to generate a genetic linkage map integrating Pan I and multiple Hb loci.

Findings

Data generated allowed the mapping of nine Hb loci, the Pan I locus, and other 122 SNPs onto an existing linkage genetic map for Atlantic cod. Four Hb genes (i.e. α1, α4, β1 and β5) have been mapped on linkage group (LG) 2 while the other five (i.e. α2, α3, β2, β3 and β4) were pl
