A genealogical DNA test is a DNA-based genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or (with lower reliability) to estimate the ethnic mixture of an individual. Since different testing companies use different ethnic reference groups ...
Haplogroup A is a human Y-chromosome DNA haplogroup, which includes all living human Y chromosomes.Bearers of extant sub-clades of haplogroup A are almost exclusively found in Africa (or among the African diaspora), in contrast with haplogroup BT, bearers of which participated in the Out of Africa migration of early modern humans.

Human genomes include both protein-coding DNA sequences and various types of DNA that does not encode proteins. The latter is a diverse category that includes DNA coding for non-translated RNA, such as that for ribosomal RNA , transfer RNA , ribozymes , small nuclear RNAs , and several types of regulatory RNAs .
In Israel, DNA testing is used to determine if people are eligible for immigration. The policy where "many Jews from the former Soviet Union (FSU) are asked to provide DNA confirmation of their Jewish heritage in the form of paternity tests in order to immigrate as Jews and become citizens under Israel's Law of Return" has generated controversy.
The collective data from this panel provides a genetic profile, or ‘DNA fingerprint,’ representing the individual. [3] To complete the diagnostic testing cycle for cancer, the genetic profile from the putative malignant specimen(s) is compared with the genetic profile derived from the patient’s DNA reference sample taken via cheek swab at ...
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). [ 2 ]
