A Y-DNA haplotype is a persons Y-STR profile. This includes the number of repeats at specific Y-STR markers. Y-DNA haplotypes are useful for tracing recent paternal lineages and connections. Y-DNA haplogroups are determined by testing Y-SNPs.Your Y-DNA haplogroup represents “deep ancestry” or ancient family group.

Y-DNA studies show that all men living today are descendants of a single root paternal ancestor who lived in Africa approximately 150,000 years ago. Over time, our ancestors migrated out of Africa in waves and populated the world. All males can be traced to one of these main Y-DNA haplogroups.
