The NCBI Map View search for adh1 on the maize genome produces these results. “Ideogram view” highlights chromosome 1 to show that the adh1 gene is located on chromosome 1. Depending on the origin of the query sequence you use to find the gene, they might show different hit scores from these versions of the gene.
