Level of Inbreeding. Based on the pedigree (details of which are given in SI Materials and Methods and Table S1), close inbreeding resulting in F ped = 0.25 is rare (n = 10 instances), and occurred only via father−daughter matings (in line with refs. 22 and 24).To minimize bias, F ped-based analysis was restricted to individuals for whom it was, at minimum, clear whether or not they were the ...

Inbreeding reduces reproductive fitness in naturally outbreeding species, and to a lesser extent in naturally inbreeding species. For example, in the 1870s Darwin found that self-fertilization reduced seed production by an average of 41%, compared to cross-fertilization, based on studies of 23 species of plants.
