Welcome to Labrador Retrievers!

 

Labrador Retrievers have now joined the team- “Team Diversity”!  

We are excited to welcome them to the family here at BetterBred and hope we can guide them along the path of “breeding for diversity,” which will always include the current arsenal of knowledge we breeders have, like temperament, health testing, structure, pedigree research etc.

 

 

The Labrador Retriever community began the research phase in November 2017, generously funded by an advocate for the breed.  The initial sample for the first 100 Labradors were selected from as diverse lines from around the world as possible, and we believe the initial sample to be a very good representative of the breed.

First certificates will be released starting on March 20-21, 2018!

Some Breed statistics:

DLA – a look at the immune system

19 class I and 17 class II DLA haplotypes – this is a large number of DLA haplotypes comparative to other breeds!

The most common DLA haplotypes are:  

  • Class II 2048 and Class I 1065, represented 38% of the tested alleles
  • Class II 2080 and Class I 1165 represented 16.7% of the tested alleles

The other DLA types in the population are much less well represented.

Genetic diversity – how much diversity exists at the population level

At each locus, there is an average of 7.13 alleles per locus.  Of those, 3.69 of the alleles are effective, meaning these alleles well represented within the population.  In comparison to other breeds, this demonstrates that Labradors Retriever breeders have done a fairly good job maintaining existing diversity and distributing it well throughout the breed. 

 

Soon Labrador Retrievers will be added to our breed comparison page!  In addition,  click here to see the the Labrador Retriever breed page on BetterBred.  Once results are uploaded, this is where the most recent 10 uploaded Labrador Retrievers can be found, as well as breed averages for IR (internal relatedness), OI (outlier index) and AGR (average genetic relatedness).

The Labrador Breeders will have a free one month trial with us at BetterBred, please click here to enroll if you were a participant in the Labrador Research Phase 1.

If you are a member of a breed community and concerned about the diversity in your breed, please contact us to discuss enrolling your breed!  We look forward to welcoming more breeds in upcoming months.

Welcome again to Labrador Retriever Breeders!  Together we will conserve your breed for the future!
