What is DNA & It Types For Genetic Genealogy

What is DNA & It Types For Genetic Genealogy Deoxyribonucleic acid is a molecule that carries most of the genetic instructions used in the development, functioning and reproduction of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life. 4 Types of DNA For Genetic Genealogy There seems to be a lot of confusion about the different "kinds" of DNA and how they can be used for genetic genealogy. X Chromosome has special inheritance properties that allow people to use these results separately from the rest of the autosomal results, although the X chromosome is a part of the 23 sets of chromosomes used for autosomal testing. The inheritance paths are different for males and females, because males only inherit an X chromosome from their mother (and a Y from their father which makes them male), but women inherit an X from both of their parents. X Chromosome Y chromosome which is passed from father to son, along, in most cases, with the surname. Only men can test for this, because only men have a Y chromosome, leaving female genealogists with Y chromosome envy, having to go and beg their fathers, brothers, uncles and male cousins to test for the surnames in question. We compare the results of the Y chromosome test between males to see if they match and are related in a genealogical timeframe. Y Chromosome Autosomal DNA – tests the rest of the DNA provided by both parents on the 23 chromosomes, not just two direct lines, as with Y-line and mitochondrial DNA. Autosomal Recessive Cerrier Mesther Older tests of this type tested between 21 and about 300 markers, but current generation testing provided by Family Tree DNA (Family Finder test), 23andMe and AncestryDNA Canier Undinced Crila Attectea Canier Autosomal DNA Mitochondrial DNA is passed from mothers to both genders of her children, but only passed on by females. Males carry their mother's mitochondrial DNA (mtDNA) but they don't pass it on. We compare mutations to see of people share an ancestor in a genealogical timeframe, but because the surname changes in every generation, it's more difficult genealogically to make the connections.
