  Examples of genetic conditions that are more common in particular ethnic groups are sickle cell disease, which is more common in people of African, African American, or Mediterranean heritage; and Tay-Sachs disease, which is more likely to occur among people of Ashkenazi (eastern and central European) Jewish or French Canadian ancestry. It is.   A genetic variation which evolved to protect people of African descent against malaria has now been shown to increase their susceptibility to HIV infection by .   Scientists have completed a comprehensive study of genetic diversity in Sub-Saharan Africa. The African Genome Variation Project analysed the DNA of 1, people . "This study has broad implications for understanding how genetic variation impacts any trait or disease," said Vijay Sankaran of Broad's Program in Medical and Population Genetics and Dana-Farber/Boston Children's Cancer and Blood Disorders Center, who was co-lead author on one of the studies with Nicole Soranzo from the Wellcome Sanger.

Heritability is the fraction of phenotype variation that can be attributed to genetic differences, or genetic variance, among individuals in a population. The greater the hereditability of a population’s phenotypic variation, the more susceptible it is to the evolutionary forces that act on heritable variation.   The study contributes a new major source of African genomic data, which showcases the complex and vast diversity of African genetic variation and which will support research for decades to . In ethnic groups with a smaller range of genetic variation due to the group's size and history, most members share many SNPs, and it may be difficult to distinguish people who have a relatively recent common ancestor, such as fourth cousins, from the group as a whole. Genetic ancestry testing is offered by several companies and organizations.

This study contributes a major, new source of African genomic data, which showcases the complex and vast diversity of African genetic variation.

And it will support research for decades to come. Our findings have broad relevance, from learning more about African history and migration, to clinical research into the impact of specific variants on. African, American, and European researchers working in collaboration over a year period have released the largest-ever study of African genetic data—more than four.

Africa is where modern humans evolved and is the starting place for the global expansion of our species (Stringer and Andrews ; Stringer ; Templeton ).African populations also have the highest levels of genetic and phenotypic variation among all humans.

This variation is informative for characterizing demographic history in Africa, including times when populations increased in size.

The worldwide pattern of single nucleotide polymorphism (SNP) variation is of great interest to human geneticists, population geneticists, and evolutionists, but remains incompletely understood. We studied the pattern in noncoding regions, because they are less affected by natural selection than are coding regions.

Thus, it can reflect better the history of human evolution and can. The findings have wide relevance, from learning more about African history and migration to specific variants of people’s health.

Africans have more genetic variation than anyone else on Earth, according to a new study that helps narrow the location where humans first evolved, probably near the South Africa.

Chapter 34 discusses genetic diseases affecting the North African population on the basis of literature mining, and discuss their spectrum, phenotypic peculiarities, and consequences for public health.

The conclusions of population genetics regarding the British Isles in turn draw upon and contribute to the. This study contributes a major, new source of African genomic data, which showcases the complex and vast diversity of African genetic variation.

And. The genetic history of Europe since the Upper Paleolithic is inseparable from that of wider Western aboutyears ago ( ka) a basal West Eurasian lineage had emerged (alongside a separate East Asian lineage) out of the undifferentiated "non-African" lineage of ka.

Both basal East and West Eurasians acquired Neanderthal admixture in Europe and Asia. A New Study Puts Africa's Genetic Diversity on Display. Our findings have broad relevance, from learning more about African history and migration, to.

More than a quarter of the genetic variation found among people in 25 Ugandan villages has never previously been recorded, because most human genetics studies focus on people. Studying the variations in different people’s genomes gives important clues to how genetic information influences people’s appearance and health.

It can also tell us about our ancestry. To date, very few African individuals have been included in studies looking at genetic variation. A genetic disease is any disease caused by an abnormality in the genetic makeup of an individual.

The genetic abnormality can range from minuscule to major -- from a discrete mutation in a single base in the DNA of a single gene to a gross chromosomal abnormality involving the addition or subtraction of an entire chromosome or set of chromosomes. History Of Genetic Disorders.

A genetic disorder can be defined as an illness that is brought on due to certain changes taking place in the genes and/or chromosomes. While diseases like cancer can be caused to changes and alterations in the genes, they can.

Africa early in the history of modern African popula-tions and that a subset of this northeast African popu-lation migrated out of Africa and populated the rest of the globe (FIG.

Analysis of mt20,21,40 and Y-chromosome diversity24–26,46 support a single East African source of migration out of Africa. Demographic history of African. The researchers analyzed genetic variation in thousands of people with each of the five disorders, and compared the genetic codes with those of people who did not have the conditions.

The birthplace of modern humans, Africa, has the highest genetic diversity in the world, yet it remains vastly understudied. With biomedical research increasingly focused on human variation, studying the large population size and number of mutations in African genomes could unravel the complexity of phenotypic traits underlying the biology of.

Africa is the source of all modern humans, but characterization of genetic variation and of relationships among populations across the continent has been enigmatic.

We studied African populations, four African American populations, and 60 non-African populations for patterns of variation at nuclear microsatellite and insertion/deletion markers. These include how genetic variation was reduced by population crashes due to introduced diseases and genocide, but also how new variation entered populations through the migration of people from.

Analysis of the genomes of hundreds of people from across Africa has shed light on ancient migrations and modern susceptibility and resistance to disease, revealing unexpected genetic .The study contributes a new major source of African genomic data, which showcases the complex and vast diversity of African genetic variation and which will support research for decades to come.

The genetic variation of whole the species is usually termed as genetic diversity. The differences in genes or DNA segments are genetic variations and each variation of a gene is termed as an allele.

For instance, there is a high amount of genetic variation in a population of several different alleles at a single chromosome locus.
