In the 1980s and '90s, a push to lower the legal blood alcohol content (BAC) limit for getting behind the wheel took the country by storm. Mothers Against Drunk Driving (MADD) was formed in 1980 ...
The existence of limits in artificial selection experiments was discussed in the scientific literature in the 1940s or earlier. [1] The most obvious possible cause of reaching a limit (or plateau) when a population is under continued directional selection is that all of the additive-genetic variation (see additive genetic effects) related to that trait gets "used up" or fixed.

Drunk driving is the act of operating a motor vehicle with the operator's ability to do so impaired as a result of alcohol consumption, or with a blood alcohol level in excess of the legal limit. [1] For drivers 21 years or older, driving with a blood alcohol concentration (BAC) of 0.08% or higher is illegal.
The direct selection for biological traits through fishery practices is the result of fishery management regulations, and gear restrictions and selectivities. [1] The most obvious artificial selection for traits through management legislation can be observed in the imposed regulations on size (minimum landing size), sex, seasonality, and locations.
Natural populations threatened by extinction are under stress by invasive pests or pathogens that have increased resistance to pesticides and antibiotics. [ 14 ] These populations may also be constrained by the genetic variation present because of the lack of sufficiently resistant alleles being able to propagate.
Haldane (1957 [= The Cost of Natural Selection]) drew attention to the fact that in the process of the evolutionary substitution of one allele for another, at any intensity of selection and no matter how slight the importance of the locus, a substantial number of individuals would usually be lost because they did not already possess the new ...
The final report of the U.K.'s infected blood inquiry was published on Monday, nearly six years after it began looking into how tens of thousands of people contracted HIV or hepatitis from ...
After 200 generations, they used E&R approach to identify genomic regions that were selected by natural selection in the hypoxia adapted flies. [30] More recent experiments are following up E&R predictions with RNAseq [ 31 ] and genetic crosses. [ 9 ]
