Editors of Nature Genetics say that "[they] hope that this will raise awareness and inspire more rigorous designs of genetic and epidemiological studies". [ 101 ] A 2021 study that examined over 11,000 papers from 1949 to 2018 in The American Journal of Human Genetics , found that "race" was used in only 5% of papers published in the last ...
In the 1970s reboot of Wonder Woman, the white-skinned Diana has a black-skinned twin sister named Nubia, who was kidnapped at birth by Ares and is historically DC Comics' first black superheroine. Though Nubia's story has been retconned over the years since her first appearance, her original identity as Diana's fraternal twin sister was retold ...

Background selection describes the loss of genetic diversity at a locus due to negative selection against deleterious alleles with which it is in linkage disequilibrium. [1] The name emphasizes the fact that the genetic background, or genomic environment, of a mutation has a significant impact on whether it will be preserved versus lost from a population.
The incidental purging of non-deleterious alleles due to such spatial proximity to deleterious alleles is called background selection. [4] This effect increases with lower mutation rate but decreases with higher recombination rate. [5] Purifying selection can be split into purging by non-random mating (assortative mating) and purging by genetic ...
Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration.
Genetic variation is the result of mutations, genetic recombinations and alterations in the karyotype (the number, shape, size and internal arrangement of the chromosomes). Any of these changes might have an effect that is highly advantageous or highly disadvantageous, but large effects are rare.
The metaphase chromosomes are treated with trypsin (to partially digest the chromosome) and stained with Giemsa stain. Heterochromatic regions, which tend to be rich with adenine and thymine (AT-rich) DNA and relatively gene-poor, stain more darkly in G-banding.
