The Havanese breed is based on the now extinct Blanquito de la Habana (little white dog of Havana), which descended in turn from the also extinct Spanish Bichon Tenerife. The Blanquito was bred with breeds of similar Bichon type and to Poodles to create the modern Havanese. It was officially accepted as a breed by AKC in 1996 and comes in a variety of colors.

Havanese are a genetically diverse and healthy breed. They have some issues that are typical of small dogs, like patellar luxation, Legg-Calve-Perthes and liver shunts, but they are not highly frequent. Maintaining overal diversity will help keep these infrequent.
The research for the Havanese breed regarding gene flow and inbreeding indicates that breeders are currently doing a pretty good job creating heterozygous dogs and maintaining the genetics they have retained from their ancestors. Breed average IR of .03 indicates some level of inbreeding within the population.
The breed has an average effective allele frequency of 4.48, with overall allele frequencies being an average of 8.576. Though this is very good for a purebred dog, this indicates opportunity to have higher effective alleles in the population.

Havanese possess considerable genetic diversity in both DLA class I and II regions, similar to that of the Miniature Poodle and much greater than breeds such as the Akita, Black Russian Terrier, Italian Greyhound, Flat-coated retrievers, and Alaska Klee Kai. This diversity involves 35 different STR-associated DLA Class I and 27 DLA Class II. Several DLA types are unique to the Havanese 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.
