About Face: Forensic Genetic Testing for Race and Visible Traits

Published online by Cambridge University Press:  01 January 2021

Extract

“DNAPrint Genomics, Inc. has applied the most recent advancements in human genomic technology for the deciphering of an individual's race. We are proud to introduce to the forensic community DNA WITNESS 2.0, a genetic test for the deduction of the heritable component of race, called Biogeographical Ancestry (BGA).”

–Z. Gaskin

“One definite and obvious consequence of the complexity of human demographic history is that races in any meaningful sense of the term do not exist in the human species.”

The terms “genetic sequence” or “DNA sequence” refer to the ordered arrangement of the four DNA building blocks, or nucleotides, which are often denoted by the initials A, C, G and T. The particular order in which nucleotides are strung together encodes genetic information. The term “DNA structure” describes something more than the nucleotide sequence; it also includes chemical modifications to the DNA, such as the methylation of some nucleotides, and the three-dimensional configuration of the DNA. In some cases, the structure might include proteins that are bound to or associated with the DNA.Google Scholar

This argument is not logically valid, because conclusion (3a) is ambiguous and does not follow from premises 1 and 2. A trait may be encoded by a single gene, such that possessing a particular allele of that gene leads to a particular version of the trait, yet more than one allele, or more than one gene, may encode that trait. For instance, suppose allele A of the hypothetical Hair Color gene is a dominant allele, and that anybody who possesses a single copy of allele A will have black hair. It could still be the case that other alleles of the HairColor gene, or alleles of genes other than HairColor, encode black hair. In such situations, knowing that a person possesses allele A would allow an observer to predict that the person would have naturally black hair, but knowing that the person has naturally black hair would not allow the observer to infer that the person possesses allele A. Even when a gene strongly determines a trait, two people may possess the same trait yet not possess the same alleles encoding that trait.Google Scholar

Genetic variation is only one form of biological variation. Many kinds of biological variation are neither determined by nor reducible to genetic variation. Some biological variation may correlate with race yet not be caused by genetic variation. Many health disparities probably fall into this category.Google Scholar

This claim should be qualified. In some research, some of the markers used might be within a disease-associated gene, but because of the manner in which the markers are chosen and the research is conducted, the researchers would not know that one of their markers was in a “disease gene.” If commercial ancestry testing firms are using any known disease-associated markers in their analyses, they have not disclosed this information.Google Scholar

Hispanic/Latina identity has been quite contested throughout US history and remains so today. Although the U.S. government considers Hispanic an ethnicity, and therefore views it as possible for a person to be Hispanic and a member of any race, many Hispanics designate their race as “other” on the census, perhaps because they do not experience themselves as belonging to one of the “big four” races, see Lopez, I. H., “Race on the 2010 Census: Hispanics and the shrinking White Majority,” Daedalus 134 (2005): 4252, (noting that in 1990, 97.5% of the people choosing “other race” on the census form also checked Hispanic ethnicity, p. 45). In much of the biomedical and genetics literature, the term Hispanic is treated as a race insofar as being Hispanic is viewed as mutually exclusive with being white, American Indian, or African American. Here, I use Hispanic as an ethnicity, and choose the relatively common representation of a white Hispanic person and a non-Hispanic Native American person. My use of this example should not be seen as an endorsement of any particular conception or usage of the term Hispanic.CrossRefGoogle Scholar

Strum, R. A. Box, N. F. and Ramsay, M., supra note 91, at 720 (1998). Normal variation in human skin color involves mixtures of at least two pigment types-red-yellow pheomelanin and black-brown eumelanin (Barsh, G. S., supra note 8, at 19). People with carrot-red hair, fair skin and freckles make large quantities of pheomelanin and small quantities of eumelanin relative to people with other phenotypes. In populations where red hair and fair skin are common, such as people of English or Irish ancestry, this “carrot-top” phenotype can be caused by a loss-of-function mutation in the melanocortin 1 receptor gene (MC1R). Certain combinations of rare MC1R variants may also cause blonde hair. However, red and blonde hair phenotypes also can be caused by genes other than MC1R. Furthermore, variation in the MC1R gene plays little role in average skin color variation between racial groups. Id. Diet, sun exposure, gender, age and other as yet unknown determinants also play some role, Roh, K. Y. et al., supra note 8.Google Scholar

For instance, if it could be shown that trait genetic testing improved the apprehension rate for perpetrators of crimes in minority communities, then minority communities with disproportionately high crime rates might benefit. This benefit would only occur, however, if police divisions or departments that served minority communities possessed the resources to obtain proper training in sample collection and preparation, and to pay for genetic tests.Google Scholar
