Reference RH and SV haplotype models. The purple border arrows indicate the joining point of homologous recombination; red border arrows indicate the joining point of nonhomologous junction; yellow filled arrows indicate the same joining points in different SV. (A) Reference RH haplotype model. (B-C) Models of the SV haplotype of the father. (D-E) Models of the SV haplotype of the mother.
