Hi Audrey. The yDNA and mtDNA tests that are being conducted in genetic genealogy do not yield a unique result. If no one matches your result, it means that the people who match you haven't been tested.
The markers you mention are a few of the many markers used by various testing companies. There is no correlation between these markers (or any of the others used in a yDNA or mtDNA test) and race, ethnicity, hair color, etc.
