The search for overrepresentation of gene ontology
terms was not conclusive. Nevertheless, some regions
can be highlighted because of their genic content and/or
results from previous studies identifying them as being
under selection. The BTA7:47.2-53.7 Mb region (Table 1:
regions P10 and P11) harbors two closely linked regions
that are potentially under selection. These regions contain
a number of immune-related and imprinted genes
(CD14, HSPA9 and PCDH family) previously identified
to be under selection, and associated with cattle fertility
(SPOCK). Moreover, a number of CNV are located in
the same region and linkage disequilibrium (LD) blocks
larger than the average genomic LD are present in both
taurine and zebu animals with LD blocks varying in
length (Additional file 4: Figure S3A). Another interesting
region is the BTA14:24.6-25.2 Mb region (Table 1:
region P22), which confirmed previous results [10] and
was recently associated with cattle production-related
traits. Interestingly, the zebu and taurine LD patterns
also markedly vary within this region (Additional file 4:
Figure S3B). The BTAX is the final region to be
highlighted, as almost the entire chromosome was
