X-Factor
The X-factor is based on the theory that the X, or female chromosome, carries certain recessive genes that result in performance factors such as large heart size. Recessive genes will only manifest themselves if inherited from both sire and dam and only if the genes are passed to individuals in a certain way. X-chromosomes can be passed from mother to son, mother to daughter and father to daughter but not father to son.
The X-factor is believed to have originated in a single female through a genetic mutation.
Such a mutation may well be behind the success of Adios whose dam is by the inbred Adioo Guy, whose own dam Adioo is a full sister to the dam of his sire Guy Dillon. The individuals involved in the inbreeding are highlighted in blue.
