Y Chromosome One of the two sex chromosomes, X and Y. The Y chromosome passes down from father to son. Females don't receive it. The fact that the Y chromosome goes down the paternal line is what makes it valuable for genealogy studies, since in general it follows a surname line.

X Chromosome X is the sex chromosome that is present in both sexes: singly in males and doubly in females.

Inheritance Chart

Branches and Twigs Haplogroups are the descents or megafamilies that characterized early human migrations. They are normally associated with geographical regions. Examples: R 1 b (Western Atlantic European), I (northern Europe), J (Jewish, Middle Eastern). Haplotype One person's set of values for the markers that have been tested. Two individuals that match on all markers but one, have two distinct haplotypes. (One-step mutation)

Markers are the site that is tested on the chromosome. Also known as sites, or loci. Names like DYS 390, DYS 285 a. Scores or values on each marker are determined by how many STRs the double helix amino acids form – Short Tandem Repeats. Also called alleles. STR - Short Tandem Repeats Known also as microsatellite, an STR is a short DNA motif (pattern) repeated in tandem. ATGC repeated eleven times would give the marker a value of 11.

What is a gene? Allele Alternative form of a gene. One of the different forms of a gene that can exist at a single locus. Bases Adenine is the "A" of the four bases in DNA that make up the letters ATGC. The other bases are thiamine (T), guanine (G) and cytosine (C). Adenine always pairs with thiamine, guanine with cytosine.

Mutation A heritable change that may occur in a gene in the form of a chemical rearrangement, or a partial loss or gain of genetic material, leading to a different number of repeats of a certain sequence (male) or change of one of the bases in a sequence (female). Mutation rate The rate at which a mutation can happen.

1. Verify the raw data for 12 target alleles from the original lab report source. 2. Control for laboratory-specific testing parameters, known validity and reliability issues, and nomenclature. 3. Perform a global search in the Y-STR Database for the haplotype. a. Search for truncated or mutational matches if unsatisfactory yield. b. Compute descriptive statistics for relevant countries. c. Establish bivariate research theses. d. Determine patterns, models, correlations, and other inferential statistics. e. Control for fast-moving markers and different mutation rates and estimate most recent common ancestor. f. Estimate risk factor of non-paternity events in line.

4. Compare search results with the other available sequence databases (Ybase, Sorenson, Family Tree DNA) a. Repeat steps 3 a. -3 f, if necessary. 5. Search DNA Surname Projects. a. Correlate branches or allonymic (other surname) genealogies. b. Repeat steps 3 a. -3 f. , if necessary. 6. Conduct chronological interactive search in relevant genealogy forums and e-mail discussion list threads at Rootsweb and other sites.

7. Search World. Cat for archival papers, special collection materials, and unique titles. 8. Check unpublished or password-protected databases, including: a. Subscriber-based information at Ancestry. com b. Melungeon DNA Surname Project (unpublished) c. Jewish. Gen (need research code) d. Scottish Clans (partially private) e. Rabbinical genealogies (largely private) f. Native American genealogies (usually requires email correspondence with owners) g. Human Genome Project (requires inputting correct gene sequence and glossary term) h. Pub. Med at the National Library of Medicine (may require publisher's password) i. Linkage literature and deep history of genotype (highly specialized).

9. Read any library articles or order any required extra materials such as interlibrary loan books. 10. Adjust inferences and retest research thesis. 11. Conduct general Internet keyword and natural phrase searches. 12. Assemble data, design report, identify relevant standard definitions, maps, scientific boilerplate, disclaimers and notes, write thesis and customized highlights. 13. Compose in HTML, with correct links, illustrations, charts and references. 14. Save file in sendable format (usually zipped), back up, and store.

Atlantic Modal Haplotype DYS 388 12 DYS 390 24 DYS 391 11 DYS 392 13 DYS 393 13 DYS 394 14 (also known as DYS 19) If you have one mutation in either direction, then you are AMH 1. 15+. The AMH 1. 15 haplotype is also referred to as the Atlantic Modal Cluster or AMC. Generally 1. 15+ puts you in haplogroup 1 (H 1), but not always.
