The wireless data exchange standard Bluetooth uses a variety of protocols. Core protocols are defined by the trade organization Bluetooth SIG. Add protocols have been adopted from other standards bodies. This article gives an overview of the core protocols and those adopted protocols that are widely used. The Bluetooth protocol stack is split in two parts: a controller stack containing the timing critical radio interface, and a host stack dealing with high level data.
DNA Origins is a unique test in that it gives you percentages of your ancestral makeup based on markers across your 22 pairs of autosomes (non-sex chromosomes); therefore, it takes into account contributions from your full spectrum of ancestors.
The X and Y Chromosomes Determine Your Sex. One chromosome from each of your 23 pairs came from each of your parents. The two chromosomes of a pair (except for the sex chromosomes) contain the same genes, but the genes have small differences. Things like SNPs make each copy of a gene uniquely Mom's or Dad's.
