Table 1.

Distribution of study dogs based on breed status and genotype

	WT/WT	WT/MUT	MUT/MUT	Total
Purebred	14.9%	47.1%	11.5%	73.5%
F1 offspring	1.2%	1.2%	0.0%	2.4%
F2 offspring	2.3%	13.7%	2.3%	18.3%
F3 offspring	1.2%	3.4%	1.2%	5.8%

Purebred Kromfohrländer as well as different offspring generations from a cross breeding program with Dansk-Svensk Gårdshund (Danish–Swedish Farmdog) where included in this study. The distribution based on the breed status and the corresponding genotype (wild-type (WT/WT), heterozygous (WT/MUT), homozygous (MUT/MUT)) is shown in this table. With 73.5% most study dogs where purebred Kromfohrländer followed by 18.3% F2 offspring. Genotype distribution shows a clear shift to heterozygotes (WT/MUT) within all 4 breed states
