Haplogroup:

A haplogroup is a group of descendant individuals from a single founder who all share a common SNP mutation. Individuals can test for these SNPs to determine their haplogroup assignment, which is often reflective of distant geographic ancestry. Membership in a particular haplogroup thus indicates broad population and geographic ancestry while other mutations in descendant haplotypes can reflect recent genealogical ancestry.

SNPs:

A SNP (single nucleotide polymorphism) is a variation in DNA sequence between individuals involving a difference at a single base-pair. SNPs generally have lower mutation rates than STRs and are often sufficiently stable to robustly define haplogroups.

"Private" SNPs:

"Private" SNPs on the Y chromosome correspond to relatively recent mutations that have not yet been observed in a significant number of other individuals in the same haplogroup. Some of these will eventually be incorporated into the Y-tree with further research. Others may provide clues about recent genealogical ancestry.

STRs:

STR (short tandem repeats) are a type of molecular marker consisting of short DNA letter repeats (such as CACA). These markers have a high rate of mutation and are accordingly useful in determining population genetic differences. In the Y chromosome line, SNPs and STRs in conjunction serve to show differences between individuals and groups in their DNA lineages. In short, STRs are one part of the puzzle in everyone's Y chromosome DNA heritage.
