Inbreeding in the united states.

Academic inbreeding has been found to occur in all higher education systems worldwide. It has even been observed in some academic sub-disciplines in the United States and the United Kingdom, where the practice has been largely eradicated at the system level (e.g., Arismendi and Penaluna 2016).For the captive population, the average pedigree-based inbreeding coefficient was F Ped_5gen =0.013. However, pedigree founders were already related by an average F Ped_18gen of 0.030 ( Forstmeier et al., 2004 ). Thus, the birds from our captive population had an F Ped_23gen of approximately 0.030+0.013=0.043.The West Virginian family has a long and complicated history of inbreeding with early reports stating that the three siblings’ now-deceased mom and dad were brother and sister.

The trends in inbreeding were linear for RDC, MRY and SKB, whereas there was a large year-to-year variation for the other breeds. The increase in inbreeding for the entire studied population coincided with an increase in the number of animals of the MRY and RDC breeds (numbers not shown).
