     NCBI's Eukaryotic Genome Annotation Pipeline</a>
     for the NCBI Gene dataset using a combination of protein sequence similarity
     and local synteny analysis. Orthology is determined between the genome being annotated and a
     reference genome, such as human or zebrafish, and pairs of orthologs are grouped together.
     Transitive relationships are inferred within each group, for example, zebrafish &lt;-&gt;
-    human &lt;-&gt; mouse. This track is available for the following assemblies: hg38, mm39,
-    danRer11, canFam6, and bosTau9.
