Duffy (white) genes in a black Baltimore population
Journal of the National Medical Association
|April 1, 1984
Summary
A study of 722 Black hospital patients in Baltimore found that 36.28% possess Duffy antigens, a significant finding for understanding genetic diversity. This research establishes a genetic benchmark for this population group.
Area of Science:
- Genetics
- Anthropology
- Hematology
Background:
- The Duffy antigen system is a significant red blood cell antigen group.
- Previous studies have explored Duffy antigen frequencies in various populations.
Purpose of the Study:
- To determine the prevalence of Duffy antigens in a large cohort of Black individuals in Baltimore.
- To establish a genetic benchmark for the Baltimore Black population.
- To facilitate comparisons with other Black populations nationally and internationally.
Main Methods:
- Blood samples were collected from 722 Black hospital patients in Baltimore.
- Testing was performed to identify the presence of Duffy antigens.
Main Results:
- 36.28% of the tested Black hospital patients in Baltimore were found to possess Duffy antigens.
- This cohort represents the largest group of Black individuals examined for Duffy antigens in the United States to date.
Conclusions:
- The findings provide crucial data on Duffy antigen prevalence in the Baltimore Black population.
- This study offers a valuable genetic reference point for future research and population comparisons.

Overview
01:39Epistasis
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
01:25What is Population Genetics?
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.While some alleles of a given gene might be observed commonly, other variants...
01:49Hardy-Weinberg Principle
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.In the early 20th century,...
02:32Position-effect Variegation
In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.
01:43Incomplete Dominance
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
