Loci associated with the number of times bred to achieve a pregnancy in Holstein heifers. Loci associated with the number of times bred to achieve a pregnancy in Holstein heifers in an additive model (Panel A), a dominant model (Panel B) or a recessive model (Panel C) of EMMAX using an IBS matrix and an uncorrected significance threshold of p < 5 × 10⁻⁸ (black line). All figures have bovine chromosomes on the x axis with −log10 p value on the y axis. As all of the animals were heifers, the Y chromosome is not shown.
