Table 1 Data set information and animal model results for autosomal crossover count (ACC). Numbers in parentheses are the standard error, except for Mean, which is the standard deviation. Embedded Image Embedded Image and Embedded Image are the number of ACC measures, the number of focal individuals (FIDS) and the total number of crossovers in the dataset. The mean ACC was calculated from the raw data. Embedded Image and Embedded Image are the phenotypic variance and additive genetic variance, respectively. Embedded Image Embedded Image and Embedded Image are the narrow-sense heritability, the permanent environment effect, and the residual effect, respectively; all are calculated as the proportion of Embedded Image that they explain. The additive genetic components were modeled using genomic relatedness matrices. Embedded Image is the significance of the Embedded Image term in the model as determined using a likelihood ratio test
