Flat coated retrievers were developed in the UK to be hunting bird dogs from ancestors imported from North America like the St. John’s water dog and the Newfoundland. Founders also included collie-like dogs and Setters. The breed was officially recognized in 1915. Only a small number of dogs existed after World War II, but careful management by breeders brought their numbers back up. This suggests evidence of at least one bottleneck in the population.

Flat Coated Retrievers have only a comparatively small portion of the diversity that exists today in modern village dogs, evidence of one or more genetic bottlenecks in the breed. One half of Flat Coated Retrievers, when assessed with village dogs, had IR values that ranged from +0.304 to +0.633. Since the average IR of offspring of full siblings is 0.25, that means that half of Flat Coats when compared to village dogs are more inbred than dogs whose parents are full siblings. This highlights the necessity for Flat Coated Retriever breeders to be very careful to avoid further overall inbreeding which leads to further loss of diversity.
The population of 190 Flat-Coated Retrievers first tested had an average number of alleles of 5.182. This number is low compared to other breeds that have been tested, once again confirming that there is a low level of genome wide genetic diversity in the breed. The mean effective alleles per locus were 2.592, also one of the lower effective allele values that we have observed. However, the distance between the average and effective alleles shows the breed community has done a reasonably good job of retaining what diversity exists.

Nine STR-associated DLA Class I and 10 DLA Class II haplotypes in 292 Flat-Coated Retrievers have currently been found. Two Class I haplotypes are unique to the breed (1142 and 1143) while all the others have also been found in other breeds. This is the second lowest amount of DLA found to date in a breed.
The follow includes dogs with birthdates listed in the database.
DLA Haplotypes in the Breed
The Dog Leukocyte Antigen or DLA is the region in the canine genome that controls the immune system, among other things. There are three classes or areas, and the VGL Canine Diversity Test genotypes or records the two regions with the most variation. Because it is an area that mutates more rapidly than others, the method VGL uses is ideal for identifying specific combinations of DNA, and not merely showing whether a dog inherited two of the same sets of genetics from its parents or two different ones.
"Haplotype" is a generic name for a set of genes that are bound together and inherited as a set. The DLA Class I and Class II haplotypes are very tightly bound and represent about 2 million base pairs of DNA - a sizeable chunk. These two haplotypes together make an extended haplotype that is nearly always passed from parent to puppies as a pair. We therefore have two tables below showing both the combinations of DLA found in this breed and how often they appear, and also how often they appear individually.
Remember that frequency percentages do not show how many dogs carry them, but rather how many of these haplotypes exist in the breed as a whole. Every dog has two sets of DLA haplotypes, one inherited from dam, and one inherited from sire. These almost never recombine in new generations.
