The association results obtained fr

The association results obtained from the absence or presence models and the copy number models appear to match. For variant A, the absence of this variant was associated witha higher MFD than the presence of either one copy or twocopies of the variant (see Table 2). This compares favourablywith the single-variant absence or presence models, whichreveal that the absence of variant A is associated with in-creased MFD, when compared to the presence of A (see Ta-ble 1). For variant C, goats that had one copy of this varianthad no difference in MFD compared to goats that did nothave variant C. This effect of variant C was not observed inthe single-variant absence or presence models, but the find-ing might have been biased by the reasonably small numberof CC goats investigated (n = 19).
