Abstract:
Microsatellite markers for Atlantic cod (Gadus morhua) were identified from a collection of 30 630 expressed sequence tags. Primers were designed for 395 microsatellites and 155 were successfully amplified. Allele number varied from 1 to 26 (average 6.34). Average observed and expected heterozygosities were 0.50 and 0.54, respectively. A subset of 105 microsatellites tested for Mendelian segregation showed no significant distortion of segregation when correcting for multiple tests. Null alleles were detected at four loci. Significant blastx matches were found for 23 loci. These microsatellites will be used to create a linkage map to enhance genetic selection in commercial cod breeding.
