[QUOTE]Originally posted by Elmaestro: [QB] [QUOTE]Originally posted by Tukuler: [qb] What's a SNP? Do SNPs define haplogroups (like our familiar nrY and mtDNA haplogroups)? Is A111T a SNP? [/qb][/QUOTE]It's similar but different, haplogroups are arbitrary... Any set of variants(aka SNP's) can be labeled as a hg. The difference is, Uniparentals don't go through recombination, the mitochondria doesn't deal with meiosis and the region we look at in the Y chromosome is non recombinant, so it doesn't swap genes or loci in that entire region (with the X chromosome). So uniparental haplogroups make it easy to detect phylogenetic structure. With autosomal haplogroups, both parents set of genes have a direct affect on the daughter hgs and you have to worry about cross over, which can hide a mutation, etc etc. If punos or BBH could tell us what happened with Xyymans threads, we can revisit how this is all relevant when I explained it the first time.
