Главное в YSEQ не стоит заказывать WGS400 как основной тест. Слишком малое покрытие и слишком много ошибок. Лучше WGS+
Интересно, а у них в описании сказано, что WGS400 как раз для генеалогии...
WGS400
This is YSEQ's Whole Genome NGS Specifically for Genealogy Researchers with 400 Base Long Reads
The whole genome contains over 200 times as much data as the Y chromosome alone! Sequencing has improved dramatically over the last seven years, which makes it not very reasonable to pay a high price for a type of sequence that only covers 70% of the Y chromosome. At a substantially lower price per base, you can get nearly 100% of the Y chromosome with YSEQ's Whole Genome test.
You’ll be able to get a complete and accurate sequence of the Y chromosome, the mitochondrial DNA, plus all the other chromosomes from 1 to 22 and of course the X chromosome.*
