S. Klein et al., GENETIC AND PHYSICAL MAPPING OF THE CHICKEN IGF1 GENE TO CHROMOSOME-1AND CONSERVATION OF SYNTENY WITH OTHER VERTEBRATE GENOMES, The Journal of heredity, 87(1), 1996, pp. 10-14
The chicken insulin-like growth factor 1 gene has been assigned to the
short arm of chromosome 1 near the centromere by fluorescence in situ
hybridization and genetic linkage analysis. Comparison of physical an
d genetic linkage maps locates the centromere between the IGF1 and GAP
D loci. Comparison of the genetic maps of chicken and other vertebrate
s reveals a highly conserved syntenic group, including the GAPD-IGF1 l
oci.
