The inbreeding coefficient ( f) is the probability that the two alleles at any locus in an individual are identical by descent (Malécot 1948 ).

Inbreeding reduces the size of the gene pool, which can lead to problems such as decreased genetic variability and the persistence of potentially harmful mutations, making it harder for the remaining population to adapt to changes in their environment.
