Figure 3.

Diagram of gene ontology of the genes which contain the highly selective SNPs in the milk protein trait. We selected the genes containing single nucleotide polymorphisms (SNPs) with p-value <0.01 (nearly top 1% SNPs) and performed gene ontology. The condition was the default value except setting 2 minimum number of genes in the gene ontology (GO) Term/Pathway selection item. The positive regulation of dendritic spine morphogenesis was the most significant gene ontology. Dendritic spine morphogenesis is important in synaptic development and plasticity of the mammalian brain.
