This chapter begins with defining and clarifying key concepts, such as ancestry, race, ethnicity, and nationality. Then it provides an overview of the enterprise of DNA ancestry testing: who the test-takers are, what their aspirations are, and how they interpret the results that they receive. ...

A location-focused DNA test for ancestry can open up new avenues for research by revealing unexpected locations where your ancestors lived and/or passed through It sheds light on the origins of family traitsCONS:It does not provide a shared database to help you locate individuals Depending on...
Heredity is complex. Given all the DNA in our genetic code, and given that we get stuff from mom and dad, there are almost infinite possible combinations of traits. Some traits aredominant, meaning they are more likely to be expressed. Some traits are recessive, meaning that they are less...
for certain diseases. Genes can acquire mutations when passed along through families, resulting in inherited conditions. Variations in an individual’s phenotype, or the sum of its observable physical or behavioral characteristics, are due part to how individual genes combine to produce those ...
Out of the hundreds of millions of cats on Earth, most of them do not have any purebred ancestors because “purebred cats” are a human invention. Cat breeds are created when humans take cats with specific traits and choose their breeding partners to create more cats with those same traits....
However,their utility is very broad, including knowingphysical and personality traits,kinship between individuals, or discovering theirancestral origins. Genetic tests are classified in many ways. They can be classified by what they analyze:cytogenetic(analyze chromosomes),biochemical(analyze changes in DN...
