This is a 2 round panel that pinpoints the terminal SNP below Z280. This panel is suggested when you have tested Z280+ or any downstream markers like e.g. CTS3402+ or Z92+.

The first round tests 4 important markers and gives you an answer to which major category you belong:
CTS1211
Y33
YP237
Z92

Depending on the results from round 1 we'll break the panel into 5 categories then.

The test is completed when the unique phylogenetic position on the tree has been determined.

See this tree diagram to understand the groupings in this panel:
