The inbreeding coefficient of Charles II
The inbreeding coefficient, written F, is the probability that a person receives at a given locus two genes identical by descent, because the parents share ancestors. Alvarez, Ceballos and Quinteiro computed it in 2009 from a pedigree of more than 3,000 people over sixteen generations.1
In their figures F rose from 0.025 for Philip I to 0.254 for Charles II, close to the 0.250 expected for the child of a brother and sister. Carlos has 0.211 and Philip III 0.218.1 Of 34 children born to the royal couples, 17 died before the age of ten. The authors propose two inherited disorders for Charles II and call the proposal highly speculative.1
