This was the first large part of the genome that was sequenced, in 1981: <Cambridge Reference Sequence>. Presumably they picked it because it is short and does not undergo <crossover>.
About 16.6 <kbp>:
* 13 coding genes
* 24 <non-coding genes>
TODO: many places say "exactly" 16,569, it seems that <variable number tandem repeat> are either rare or don't occur!
* https://pubmed.ncbi.nlm.nih.gov/2881260/ 1989 reports a single length polymorphism
