Natural selection and genetic drift are two important forces driving ... pressures as the underlying factor for this reproductive shift in S. salamandra. Our study clearly highlights the utility ...

Spontaneous mutations can lead scientists down the wrong path, but awareness in academia and new measures by industry are helping to keep genetic drift at bay. To create null-mutations in mice ...

The founder effect is an extreme example of "genetic drift." Genes occurring at a certain frequency in the larger population will occur at a different frequency -- more or less often -- in a ...

Drift is a subtler process than shift and involves the accumulation of mutations within the antibody-binding sites in the hemagglutinin (see Figure), the neuraminidase, or both that abrogate the ...
