In that study, the UChicago researchers
matched genetic markers of the «input» and «output» neurons of the mammalian neocortex with genes expressed in several bird DVR nuclei.

Molecular
markers — pieces of DNA that «mark» a specific gene — allow researchers to comb the
genetic blueprint of a plant,
match the sequence with a certain trait using computer programs, and develop seeds.
The algorithm scans more than 1800
genetic markers that have been collected and looks for
matches to breed signatures, then provides a
marker - by -
marker certainty score for each breed
match.
Furthermore, for 3 of the 4 that did have
genetic markers matching their visually identified breed, that breed contributed at most 12.5 % of their makeup.
