BetterBred’s Litter Analysis

 

This image is a genetic breeding report for a planned dog pairing from BetterBred’s data using VGL’s genetic diversity analysis for the two parents. This picture shows how two parent dogs compare and what their puppies are likely to inherit in terms of genetic diversity. In this picture two Golden Retrievers are used: Birnam Woods Too Marvelous for Words, the dad and Red-Dawn Resolute Nala, the mom.

• Top section (pairing summary):
  • Lists the sire and dam and their genetic scores (OI, IR, AGR).
  • The pairing result shows:
    • IR = -0.067 → indicates low relatedness / low inbreeding
    • Labeled as “genetic equivalent: unrelated”
    • Overall categorized as a good diversity pairing (Category 10)
• Left side definitions:
  • Explains the three key metrics:
    • OI (Outlier Index): how rare or unique a dog’s genetics are
    • IR (Internal Relatedness): how similar the parents are genetically
    • AGR (Average Genetic Relatedness): how related a dog is to the overall breed population
• Middle graphs (litter predictions):
  • Show the expected range of OI and IR in the puppies
  • Indicates the litter should have:
    • Moderate to good diversity (OI avg ~0.15)
    • Low inbreeding overall (IR avg ~ -0.03)
• DLA haplotypes:
  • Displays immune system gene variants from each parent
  • Helps predict immune diversity in the puppies
• Bottom section (puppy outcomes):
  • Shows 4 possible genetic combinations
  • Each has a 25% chance, based on how genes can be inherited
