Exempel på hur du använder DELETERIOUS i en mening

• An example of deleterious mechanically induced modulation is speckle noise created in a multimode fiber by an imperfect splice or imperfectly mated connectors.
• By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious recessive traits resulting from incestuous sexual relationships and consanguinity.
• Soil degradation may also be viewed as any change or ecological disturbance to the soil perceived to be deleterious or undesirable.
• While it was initially regarded as a recessive (or purely homozygous) disorder, some researchers have reported the existence of similarly deleterious effects from the heterozygous form of the SNP.
• The neutral theory assumes that most mutations that are not deleterious are neutral rather than beneficial.
• Nancy Wilmsen Thornhill states that the drive in humans to not reproduce or be attracted to one's immediate family is evolutionarily adaptive, as it reduces the risk of children having genetic defects caused by inbreeding, as a result of inheriting two copies of a deleterious recessive gene.
• Markers on different chromosomes are perfectly unlinked, although the penetrance of potentially deleterious alleles may be influenced by the presence of other alleles, and these other alleles may be located on other chromosomes than that on which a particular potentially deleterious allele is located.
• Hard landscapes are characterized by the maze-like property by which an allele that was once beneficial becomes deleterious, forcing evolution to backtrack.
• In evolutionary genetics, Muller's ratchet (named after Hermann Joseph Muller, by analogy with a ratchet effect) is a process which, in the absence of recombination (especially in an asexual population), results in an accumulation of irreversible deleterious mutations.
• Legal scholar Richard Collier writes that fathers' rights activists often base their arguments for reform on "anecdotal evidence and assertion" rather than "evidence-backed research", and argues that implementing their proposed changes to the law "may have potentially deleterious consequences" for mothers and children.
• Apparently, the explanation for the absence of inbreeding depression is that, over the long-term, the small population size of island foxes facilitated a reduced burden of strongly deleterious recessive mutations through genetic purging by natural selection.
• The border was drawn through the deepest channel of the Muonio and Tornio rivers, splitting Lapland into two parts, with deleterious effects on trade.
• Mutational meltdown (not to be confused with the concept of an error catastrophe) is the accumulation of harmful mutations in a small population, which leads to loss of fitness and decline of the population size, which may lead to further accumulation of deleterious mutations due to fixation by genetic drift.
• The Genetical Theory of Natural Selection is a book by Ronald Fisher which combines Mendelian genetics with Charles Darwin's theory of natural selection, with Fisher being the first to argue that "Mendelism therefore validates Darwinism" and stating with regard to mutations that "The vast majority of large mutations are deleterious; small mutations are both far more frequent and more likely to be useful", thus refuting orthogenesis.
• The latter technique has proved to be less deleterious for the embryo, therefore it is advisable to perform the biopsy around day 5 or 6 of development.
• Furthermore, homozygosity and the expression of deleterious recessive mutations as consequences of inbreeding have likely resulted in the purging of severely deleterious mutations from the population.
• Chloride ion channels have been found to play crucial roles in the development of human diseases, for example, mutations in the genes encoding chloride ion channels lead to a variety of deleterious diseases in muscle, kidney, bone, and brain, including cystic fibrosis, osteoporosis, and epilepsy, and similarly their activation is supposed to be responsible for the progression of glioma in the brain and the growth of malaria-parasite in the red blood cells.
• Attacked as blasphemous and deleterious to the public's moral well-being, the light-hearted play's performance triggered a notable legal case in which Claus was prosecuted: convicted on charges of public indecency, Claus was ordered to pay a ten-thousand-Belgian franc fine and serve a four-month prison sentence.
• Mainly through (optional) anonymization and parallelization of input, electronic meeting systems overcome many deleterious and inhibitive features of group work.
• The deleterious and unfocused effects of the EMP test led to the banning of nuclear weapons in space in the Outer Space Treaty of 1967.
