A Gene-Based Genetic Linkage Map of the Collared Flycatcher (Ficedula Albicollis) Reveals Extensive Synteny and Gene-Order Conservation during 100 Million Years of Avian Evolution
Beginning of article
ABSTRACT
By taking advantage of a recently developed reference marker set for avian genome analysis we have constructed a gene-based genetic map of the collared flycatcher, an important "ecological model" for studies of life-history evolution, sexual selection, speciation, and quantitative genetics. A pedigree of 322 birds from a natural population was genotyped for 384 single nucleotide polymorphisms (SNPs) from 170 protein-coding genes and 71 microsatellites. Altogether, 147 gene markers and 64 microsatellites form 33 linkage groups with a total genetic distance of 1787 cM. Male recombination rates are, on average, 22% higher than female rates (total distance 1982 vs. 1627 cM). …
