Modern catalogues are dominated by a few genetic families whose names recur in dozens of crosses. Most high thc strain seeds sold today trace back to lines such as OG Kush, Cookies, Gelato, or Chemdawg, which breeders combine repeatedly because their potency passes reliably to offspring. Names like these have become shorthand for a flavour and effect profile rather than a strict pedigree, and two strains sharing a name may differ in lineage. Checking the listed parents gives a better idea of what to expect than the marketing title.
