I've found that Wikipedia has really good high-level information for a lot of the subject matter. For use cases, the business sells direct-to-consumer DNA tests. I've worked on several of the analysis products' softwares. The compute-heavy workload calculates edit distance [0] of short paired-end sequenced DNA [1] vs the human genome [2]. There is open source software to manipulate the FASTA/FASTQ [3] and SAM files [4] and run the calculations [5]. The aligned file is processed in a couple of minutes to genetic variation report [6] which is used for some of the analysis products that were purchased. One popular product will give you a haplogroup [7] which basically tells you where you are in a genetic tree. The relationship estimator uses a different sequencing technology and basically consumes a CSV file from the sequencer's manufacturer. It uses a proprietary algorithm to calculate centimorgans [8]. That then gives relationship estimates between you and other people who've purchased the product.
