Inbreeding Coefficients in Dogs Inbreeding is less than 12.5% (yellow) in about half of the horse breeds, while only a handful of dogs are this low. In horses, even the maximum inbreeding values were greater than 25% in only about a third of the breeds (bottom, red line). 3 янв. 2017 г.
What is an acceptable coefficient of inbreeding for dogs?
The average COI for purebred dogs is ~20%. Specific breeds can be higher or lower than this value. For some breeds, the average coefficient of inbreeding can approach or even pass 40%. Because these are average numbers, individual COI can vary.
What is a high coefficient of inbreeding in dogs?
25% = the genetic equivalent of a dog produced from a father to daughter mating, or the mating of full-brother/sister. More than 25% - inbreeding is accumulative, so if it has occurred to a significant degree over several generations, the inbreeding coefficient may exceed 25%
What is the average coefficient of inbreeding?
Average inbreeding coefficient for the whole population was 2.68%, and the minimum and maximum inbreeding coefficients were 0.05% and 31.25%, respectively. Average coefficient of inbreeding for inbred population was 5.17% and the number of inbred animals in the population was 2777.
How inbred is the average dog?
The average inbreeding based on genetic analysis across 227 breeds was close to 25%, or the equivalent of sharing the same genetic material with a full sibling.
