“…These included 507 microsatellite-based markers developed for the turkey, chicken and quail and 8 SNPs (Chaves et al, , 2005Hall et al, 2003) corresponding to markers on the cDNA/RFLP map of Harry et al (2003). Turkey microsatellites included 416 MNT (Reed et al, 2000(Reed et al, , 2002(Reed et al, , 2003bDranchak et al, 2003;Knutson et al, 2004;Reed, unpubl), 11 TUM (Huang et al, 1999), 5 RHT (Burt et al, 2003) and 5 WT (Latch et al, 2002).…”

Genetic markers (microsatellites and SNPs) were used to create and compare maps of the turkey and chicken genomes. A physical map of the chicken genome was built by comparing sequences of turkey markers with the chicken whole-genome sequence by BLAST analysis. A genetic linkage map of the turkey genome (Meleagris gallopavo) was developed by segregation analysis of genetic markers within the University of Minnesota/Nicholas Turkey Breeding Farms (UMN/NTBF) resource population. This linkage map of the turkey genome includes 314 loci arranged into 29 linkage groups. An additional 40 markers are tentatively placed within linkage groups based on two-point LOD scores and 16 markers remain unlinked. Total map distance contained within linkage groups is 2,011 cM with the longest linkage group (47 loci) measuring 413.3 cM. Average marker interval over the 29 linkage groups was 6.4 cM. All but one turkey linkage group could be aligned with the physical map of the chicken genome. The present genetic map of the turkey provides a comparative framework for future genomic studies.

“…Recently, two genetic linkage maps were reported for the turkey. One map (Harry et al, 2003) is based on expressed genes (cDNA/RFLPs), and includes 113 markers arranged into 22 linkage groups with an additional 25 that remain unlinked. A second linkage map based on microsatellites, was reported by Burt et al (2003).…”

“…Despite the fact that the mechanism of evolution is still unclear, microsatellites are being widely employed in forensics, genetic mapping, population genetics, evolutionary studies, and investigation of social systems (Chakraborty et al 1997;Buchholz et al 1998;Chowdhury and Bansal 2001;Jernej and Branka 2001;Burt et al 2003;Harry et al 2003;Huang et al 2004;Knutson et al 2004).…”

A Genetic and Cytogenetic Map for the Duck (Anas platyrhynchos)

A genetic linkage map for the duck (Anas platyrhynchos) was developed within a cross between two extreme Peking duck lines by linkage analysis of 155 polymorphic microsatellite markers, including 84 novel markers reported in this study. A total of 115 microsatellite markers were placed into 19 linkage groups. The sexaveraged map spans 1353.3 cM, with an average interval distance of 15.04 cM. The male map covers 1415 cM, whereas the female map covers only 1387.6 cM. All of the flanking sequences of the 155 polymorphic loci-44 monomorphic loci and a further 41 reported microsatellite loci for duck-were blasted against the chicken genomic sequence, and corresponding orthologs were found for 49. To integrate the genetic and cytogenetic map of the duck genome, 28 BAC clones were screened from a chicken BAC library using the specific PCR primers and localized to duck chromosomes by FISH, respectively. Of 28 BAC clones, 24 were detected definitely on duck chromosomes. Thus, 11 of 19 linkage groups were localized to 10 duck chromosomes. This genetic and cytogenetic map will be helpful for the mapping QTL in duck for breeding applications and for conducting genomic comparisons between chicken and duck.

“…A second mapping/reference panel was used by Harry et al (2003) to create a linkage map for the turkey based on RFLP mapping of expressed sequences (cDNAs). This panel was derived from a single F 1 sire (an intercross between two commercial lines, A and B) backcrossed to two dams from line B.…”

Efforts to build a comprehensive genetic linkage map for the turkey (Meleagris gallopavo) have focused on development of genetic markers and experimental resource families. In this study, PCR amplification was attempted for 772 microsatellite markers that had been previously developed for three avian species (chicken, quail and turkey). Allelic polymorphism at 410 markers (53.1% of total examined) was determined by genotyping ten individuals (six F₁ parents and four grandparents) in a new resource population specifically developed for genetic linkage mapping. Of these 410 markers, 109 (26.6%) were polymorphic in the tested individuals, with an average of 2.3 alleles per marker. Higher levels of polymorphism were found for the turkey-specific markers (61.1%) than for the chicken (22.7%) or quail-specific markers (33.3%). To test the fidelity of the matings, demonstrate the power of these families for linkage analysis, and determine genetic linkage relationships, 86 polymorphic markers were genotyped for up to 224 birds including founder grandparents, parents and F₂ progeny. Linkage relationships for many of the chicken markers elucidated in the turkey were comparable to those observed in the chicken. These data demonstrate that the new UMN/NTBF resource population will provide a solid foundation for constructing a comparative genetic map of the turkey.
