	DYS (DNA) - Wikipedia, the free encyclopedia
		DYS is short for DNA Y-chromosome Segment, and is used to designate a segment of DNA on the Y chromosome where a sequence of nucleotides repeats.
		The possible variations of repeats at a DYS marker are known as alleles.
		DYS is often proceeded by the number sign (#), so the location 455 may be written as DYS455, DYS 455, DYS#455, or DYS# 455.

	Genealogical DNA test - Wikipedia, the free encyclopedia
		The DNA in the mitochondria (an organelle inside most cells) is generally passed down by the mother unchanged, though some exceptions have been shown.
		Genealogical DNA tests allow for an individual to determine with 99.9% certainty that they are related to another individual within a certain time frame, or with 100% certainty that they are not related to another individual within a certain time frame.
		Though genealogical DNA tests results generally have no informative medical value and do not determine genetic diseases or disorders, there has been a correlation established between a lack of DYS464 markers and infertility, and a correlation between mtDNA haplogroup H and protection from sepsis.

	Jordan Surname DNA ProjectTest Description
		The 12 marker test determines 12 DYS allele: 393, 390, 19, 391, 385a, 385b, 426, 388, 439, 389-1, 392 and 389-2.
		If, for instance, the DYS 393 allele result is off by one between two individuals and all the other numbers are equal, then it is called an 11/12 match.
		For certain locus, Dr. Hammer of the University of Arizona has not released the exact DYS number and the reported values for those particular locus are "scores," a normalized number, instead of the measured number of "repeats" representing a particular allele at that loci.

	Glossary
		DNA Marker - A gene or some non-coding segment of DNA whose location in the genome is known and whose different allele values at the location can be used to sort versions of the DNA genome into groups and/or to distinguish one DNA genome from another.
		The nomenclature for determining and counting the repeats, the allele value of the DYS, and assignment of a new DYS number is controlled by the HUGO Gene Nomenclature Committee in the effort to maintain industry standardization, e.g., DYS390 is a typical DYS location number used in Y-Chromosome haplotype tests.
		The 12 DYS marker test is used for low cost initial screening of males in a surname project, and for use in estimating the male’s Y-Chromosome Haplogroup.

		DNA Heritage has been kind enough to provide me with my electropherograms for DYS464 and to grant permission for me to post them here.
		DNA Heritage has concluded that my values are 12, 12, 15, 15, 15, 16.
		The DNA they test is found only in men and is passed down from father to son unchanged except for random mutations which happen every dozen generations or so (depending on how many markers are tested).

	DNA 101
		DNA 101 is an attempt to take the extremely complex and confusing subject of Genetics and DNA and simplify it into layman terms.
		DNA testing can be a valuable tool in genealogical research when it is combined with conventional research.
		Because DNA segments that lie near each other on a chromosome tend to be inherited together, markers are often used as indirect ways of tracking the inheritance pattern of genes that have not yet been identified, but whose approximate locations are known.

	DNA Analysis For Genealogy
		To date, DNA that has been mixed in this way has not been of use to genealogy, as there is no way to relate the offspring's DNA with those of the parents.
		This DNA is not mixed with that of the mother, and it is identical to that of the father, unless a mutation occurs.
		Y DNA within such a family group may not match, because of what are delicately called "non-paternal events." There are three causes for such events.

		The historical family origins of the majority of the DNA testers are in Co Leitrim.
		The DNA test is perhaps the only chance to begin to make those connections as many of the MacTighernan families like a smaller scale of the larger Irish Diaspora have scattered to distant lands in the world and live there today.
		If you are a close genetic match with another MacTighernan in your DNA group you may have a lot of work to do to find a common ancestor but still you are on the right path.

		DNA is made up of two long strands connected together along the middle (a bit like a zip), where bases on one strand are bonded to bases on the other side.
		Within DNA are the code-words needed to form proteins, although much of the DNA is termed 'junk DNA' and has no known function.
		In DNA they are composed of phosphate, deoxyribose (a sugar), and either a purine (for adenine and guanine) or pyrimidine (for cytosine and thymine) base.

		By analyzing the DNA from men with the Mumma surname (or spelling variations), we are researching and resolving genealogical puzzles and roadblocks.
		Hence, the DNA from very distant cousins should also match and this is the reason you don't need the DNA from a deceased ancestor to infer that person's Y-chromosome "fingerprint".

		DYS# 389-i is a sub group of of DYS# 389-ii so a mutation in both is considered as just one mutation.
		DYS# 464 is a complex of 4 identical markers, such that the only way to assign labels to them is to sort by size.
		The DYS Markers (D = DNA, Y = Y-chromosome, S = segment) define the Haplotypes that are within the Haplogroup.

	The Genealogy of Mexico
		He further tested their mitochondrial DNA (mtdna) which is a test to find the origins of your great, great...grandmother, going back 10's of thousands of years.
		This is done by examining DNA handed down strictly from father to son or DNA handed down strictly from Mother to daughter, going back thousands of years.
		Since part of our Y chromosome DNA is passed from father to son relatively unchanged for 1000's of years we can determine what haplogroup we belong to as well as narrow down the possibility of 2 people having a common male ancestor (12 marker test).

		The Hull (variants) DNA Study is presently tracing the surname using the Y-chromosome test, which is passed from father to son.
		Your mismatch will most often be found within DYS 439 or DYS 385a, 385b, 389i and 389ii from your first panel of 12 markers, or within the second panel of 25 markers at DYS458, 459a, 459b, 449, or within 464a-d.
		Testing additional individuals means that you must find the person whose DNA results falls in-between the persons that are a genetic distance of 5-steps apart that can demonstrate the relatedness you are seeking within your family cluster or haplotype.

		With the addition of markers DYS 385a and DYS 385b it further helps to pinpoint which ancient population group one is a member of.
		This group has a unique marker DYS 455 at 8 which defines it from the others of haplogroup I. Another marker DYS 390 separates the Saxons from the Norse.

	The Dekle Surname DNA Project
		The objective of this project is to match up individuals or families who share a common male ancestor with the Dekle surname and to trace the origins of the Dekle surname in America and back to Europe.
		The portion of the DNA tested gives a distinctive "signature" for a lineage rather than for an individual, so there is no risk of the data being applied to personal identity for misuse of any kind.
		Your DNA will be preserved for 25 years at no additional cost and you will be entitled to reduced "add-on" prices for other tests.

		A second objective is to use both the DNA and genealogical evidence to help Shetlanders find answers to questions about their ancestry such as whether all Hughsons are related; and if so, who was their most recent common ancestor, and when and where did this person live?
		Thirdly, it is hoped that the data emerging from the present inquiry will shed light on the apparent migration of people from Central Asia to Scanadnavia and ultimately Shetland prior to the Viking era; and also provide evidence as to whether the native Pictish people survived the Viking "settlement" in the 9th Century.
