Question: What is the average IC and the range of IC in current breedings?
Answer: Most breeders tend to look at a wide-range of data vs. relying solely on inbreeding coefficients. That being said, the chart below that reflects the range (high-and-low), the average, and the median for both inbreeding coefficient (IC) and outcross (OTX) percentages collected from litter data breed-wide.
Breed Planning IC & OTX – information reflects data recorded from 2015-2019
In general, a high IC% shows a higher old-line and/or closely related breeding; the lower the percent the more OTX involved. This report reflects breed-wide observations and no individual breeder philosophy. An individual breeder theoretically could have wide swings in IC% within their kennel depending on the specific breedings they are working on.
It is important to note that we do have some breeders that make a great effort to not report their litter information (whether it be directly, on their websites, social media, etc.). As collaborators, we do the best we can with the information we discover. The team does a pretty good job and we couldn’t do it without all of you. [submit data]
For more information on outcrosses [ report ]
- Data set is from litter information collected breed-wide
- IC calculations are based on 10G
- OTX calculations are the total of percent of blood of each OTX on 10G
- litters with incomplete data were removed prior to making these calculations
- 2016 0%* denotes an OTX litter (WSSBA)
- 2017 0%** denotes an OTX litter (ISSA)
