Double recombinants of the form 1(.)2(.)1 and 2(.)1(.)2 (1, homozygote; 2, heterozygote) that may represent genotyping errors (see text) were identified for each chromosome from the MBxdatabase. (.) represents a variable number of intervening markers with no genotypes for a haplotype. Up to 10 intervening markers for which there was no genotype information were permitted. Thus, at the limit, double recombinants of genotype 1 (10 markers, no genotypes) 2 (10 markers, no genotypes) 1, and 2 (10 markers, no genotypes) 1(10 markers, no genotypes) 2 were identified. For chromosomes 1 and 5, a further round of error checking of double recombinant genotypes and reordering took place for these chromosomes to assess the underlying error rate (see text). Triple recombinants of the form 11(.)2(.)1(.)22 or 22(.)1(.)2(.)11, which may represent local misorders (see text), were also identified from MBx. Up to 10 intervening markers (.) for which there is no genotype information were again permitted.
