Yes. If you do not have a Y-DNA STR test, you will not be able to view your haplotree information.
Alternatively, you may first take the Geno 2.0 test and then transfer your results to Family Tree DNA. You will then see your Y-DNA haplotree and transferred, positive SNPs from Geno 2.0. Ordering additional SNPs or an STR test after transferring results from Geno 2.0 is up to you; however, we recommend consulting a haplogroup project administrator before deciding.
