Each subtable summarizes results for cross type (origin and gender of the parental populations), the concerned linkage groups with the marker name and genotypic data for one of six mapping families. The segregation of alleles (labeled A, B, C, D) from the dam and sire of the F1 into the F2 generation reveals a strong correlation of the offspring sex with the presence of a single paternal allele (numbers indicate individuals carrying the respective alleles. Bold numbers highlight the sex specific allele. Note that the inheritance of identical alleles cannot be resolved). This pattern is observed in a single family (ZG42) for the paternal allele on linkage group 1 from C. rhenanus and five times for the paternal allele on linkage group 2 which originates from C. perifretum.
