Families including identification number of sire and dam, number of male (M) and female (F) offspring, and sex ratio (M:F). p values are from Fisher’s exact test of association of SSR marker data with phenotypic sex, testing the sire’s alleles for Y associations, and dam’s alleles for W association, with bold values indicating p < 0.05, and NI indicating markers tested were not informative. System indicates inferred sex determination system in family from marker data within and among families. An expanded version of this table with markers used, and a table with marker genotype data is available in Additional files 5 and 6.
