A genetic dissection of breed composition and performance enhancement in the Alaskan sled dog

BMC Genomic Data

Table 2 Sled dogs were 5× lower in inbreeding and 15% higher in observed heterozygosity than purebreds.

A. F_IS is the degree of inbreeding within populations (correlation of alleles within individuals within one sub-population).
B. F_ST is the overall inbreeding coefficient (correlation of alleles of different individuals in the same population).
C. Sigma-G is the variance of alleles within individuals.
D. A is the mean number of alleles per locus.
E. He is the expected heterozygosity of a population.
F. Ho is the observed heterozygosity of a population.
G. Data set included 141 purebred breed populations (681 individual dogs).
H. Data set included 141 purebred breed populations and 2 Alaskan sled dog populations using the 5 most representative individuals of the sprint racing and distance racing styles (10 total Alaskan sled dogs).
I. Data set included all 199 Alaskan sled dogs with microsatellite data. Relatedness not accounted for.
J. Data set included 42 unrelated to the grand-parent generation Alaskan sled dog representatives of each racing style (sprint versus distance) (84 total Alaskan sled dogs).
K. Data set included the 5 most representative individuals of each sub-population found within the sprint and distance racing style (40 Alaskan sled dogs).
L. Data set included the 5 most representative individuals of each of the 4 sprint sub-populations (20 sprint Alaskan sled dogs).
M. Data set included the 5 most representative individuals of each of the 4 distance sub-populations (20 distance Alaskan sled dogs).
