Jason Ulrich, Scientific American, 1 Aug. 2021 Scientists dispute whether their rarity is because the recessive allele is the result of a one-time mutation or because white tigers lack adequate camouflage, negatively affecting their ability to stalk prey or avoid other predators. Azzedine Downes, Scientific American, 22 June 2021 To continue producing white tigers, captive tigers with this rare allele expression are intensively inbred over multiple generations. Azzedine Downes, Scientific American, 22 June 2021 In North Carolina and Indiana, where outbreaks had clear connections to the Biogen conference, nearly twenty per cent of samples contained the C2416T allele. Benjamin Wallace-wells, The New Yorker, 17 Dec. 2020 Each allele brings its individual touch to the role.Quanta Magazine, 14 Sep. 2017 For example, some of the archaic alleles Sankararaman spotted in Africans were in genes that suppress tumors and regulate hormones. Ann Gibbons, Science | AAAS, 20 Feb. 2020 Lola’s genome also contained alleles that are usually associated with the inability to produce lactase—an enzyme that’s important in digesting milk—as an adult. Kiona N. Smith, Ars Technica, 13 Feb. 2020 Each variant has a version (more precisely, one of the alleles in a single nucleotide polymorphism) associated with a small boost to the trait in question.
