We determined the quark mass matrix in terms of a small expansion parameter $$\sqrt \varepsilon $$ ε , which gives correctly all the quark masses and the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements on the electroweak (EW) scale, and we obtained a progenitor form at the grand unified theory (GUT) scale by running the EW scale mass matrix. Finally, a possible texture form for the progenitor quark mass matrix is suggested.
