“…However, studies in primates showing that diversity is reduced in humans, as compared to great apes [36], could suggest an alternative explanation for this phenomenon. In chickens, one SNP per 225 bp was observed in a survey of 31 000 bases analysed from broiler and layer lines [73] and one SNP per 2 119 bp was observed in chicken ESTs [39]. However, in these studies, the number of individuals sampled was not indicated and the heterozygosity value is therefore not available.…”

-During the last ten years, the use of molecular markers, revealing polymorphism at the DNA level, has been playing an increasing part in animal genetics studies. Amongst others, the microsatellite DNA marker has been the most widely used, due to its easy use by simple PCR, followed by a denaturing gel electrophoresis for allele size determination, and to the high degree of information provided by its large number of alleles per locus. Despite this, a new marker type, named SNP, for Single Nucleotide Polymorphism, is now on the scene and has gained high popularity, even though it is only a bi-allelic type of marker. In this review, we will discuss the reasons for this apparent step backwards, and the pertinence of the use of SNPs in animal genetics, in comparison with other marker types.SNP / microsatellite / molecular marker / genome / polymorphism

Mammalian and avian genomes comprise several classes of chromosomal segments that vary dramatically in GC-content. Especially in chicken, microchromosomes exhibit a higher GC-content and a higher gene density than macrochromosomes.To understand the evolutionary history of the intra-genome GC heterogeneity in amniotes, it is necessary to examine the equivalence of this GC heterogeneity at the nucleotide level between these animals including reptiles, from which birds diverged. We isolated cDNAs for 39 protein-coding genes from the Chinese soft-shelled turtle, Pelodiscus sinensis, and performed chromosome mapping of 31 genes. The GC-content of exonic third positions (GC 3 ) of P. sinensis genes showed a heterogeneous distribution, and exhibited a significant positive correlation with that of chicken and human orthologs, indicating that the last common ancestor of extant amniotes had already established a GC-compartmentalized genomic structure. Furthermore, chromosome mapping in P. sinensis revealed that microchromosomes tend to contain more GC-rich genes than GC-poor genes, as in chicken. These results illustrate two modes of genome evolution in amniotes: mammals sophisticated the genomic configuration in which GC-rich and GC-poor regions coexist in individual chromosomes, whereas sauropsids (reptiles and birds) refined the chromosomal size-dependent GC compartmentalization in which GC-rich genomic fractions tend to be confined to microchromosomes.2

“…A total of 258 microsatellite markers were chosen from the genetic consensus map [7] and were assessed for informativeness on the five F 1 sires. The 129 markers, chosen for the genotypings, were located on 26 chromosomes and 4 linkage groups described by Schmid et al [26]. The markers spanned 2598 cM with an average interval of 20 cM between markers, including an arbitrary 20 cM for end markers of each linkage group [8].…”

Mapping quantitative trait loci affecting fatness and breast muscle weight in meat-type chicken lines divergently selected on abdominal fatness

et al. 2006

-Quantitative trait loci (QTL) for abdominal fatness and breast muscle weight were investigated in a three-generation design performed by inter-crossing two experimental meattype chicken lines that were divergently selected on abdominal fatness. A total of 585 F 2 male offspring from 5 F 1 sires and 38 F 1 dams were recorded at 8 weeks of age for live body, abdominal fat and breast muscle weights. One hundred-twenty nine microsatellite markers, evenly located throughout the genome and heterozygous for most of the F 1 sires, were used for genotyping the F 2 birds. In each sire family, those offspring exhibiting the most extreme values for each trait were genotyped. Multipoint QTL analyses using maximum likelihood methods were performed for abdominal fat and breast muscle weights, which were corrected for the effects of 8-week body weight, dam and hatching group. Isolated markers were assessed by analyses of variance. Two significant QTL were identified on chromosomes 1 and 5 with effects of about one within-family residual standard deviation. One breast muscle QTL was identified on GGA1 with an effect of 2.0 within-family residual standard deviation.
