It is measured by a variety of parameters. Smaller genetic distances indicate a close genetic relationship whereas large genetic distances indicate a more distant genetic relationship.

Within a species genetic distance can be used to measure the divergence between different sub species.

In probability theory , stochastic drift is the change of the average value of a stochastic process stochastic random process . A related term is the drift rate which is the rate at which the average changes. This is in contrast to the random fluctuations about this average value. For example, the process which counts the number of heads in a series of math n math coin toss es has a drift rate of 1 2 per toss. Stochastic drifts in population studies Longitudinal studies of secular events are frequently conceptualized as consisting of a trend component fitted by a polynomial , a cyclical component often fitted by an analysis based on autocorrelation s or on a Fourier series , and a random component stochastic drift to be removed. In the course of the time series analysis , identification of cyclical and stochastic drift components is often attempted by alternating autocorrelation analysis and differencing of the trend. Autocorrelation analysis helps to identify the correct phase of the fitted model while the successive differencing transforms the stochastic drift component into white noise . Stochastic drift can also occur in population genetics where it is known as Geneticdrift .

In telecommunication , a drift is a comparatively long term change in an attribute, value, or operational parameter of a system or equipment. The drift should be characterized, such as diurnal frequency drift and output level drift. Drift is usually undesirable and unidirectional, but may be bidirectional, cyclic, or of such long term duration and low excursion rate as to be negligible. ref http www.its.bldrdoc.gov fs 1037 fs 1037c.htm Federal Standard 1037C ref Drift is also common in pseudo synchronised streaming applications, such as low latency audio streaming over TCP IP . Normally both ends of a streaming connection would stay in sync with a master clock but TCP IP does not provide this master clock mechanism. Therefore applications running fixed clocks will drift apart over time and glitch es will occur. This is usually fixed by controlling jitter or drift, by slightly altering the clock speed at one end of the connection. Drift can be removed from signals by signal combination. This strategy is used in optical and electrical systems such as optical tweezers . ref http rsi.aip.org resource 1 rsinak v82 i11 p115103 s1?isAuthorized no Mashaghi et al.

Unreferenced date April 2009 Image 62441 copy.jpg right thumb 200px drift punch In metalworking , a drift pin , drift pin punch , or simply drift , is the name for a tool used for enlarging holes, or aligning holes prior to bolting or riveting metal parts together. A drift pin is not used as a punch in the traditional sense of the term. A drift pin is used as an aid in aligning bolt or rivet holes prior to inserting a fastener. A drift punch is constructed as a tapered rod, with the hammer acting on the large end of the taper. The tapered end of a drift punch is placed into the semi aligned bolt holes of two separate components, and then driven into the hole. As it is driven in, the taper forces the two components into alignment, allowing for easy insertion of the fastener . Unlike most punches, force should never be applied to the tip of drift pin. Drift pins are especially useful for aligning fastener holes in structural steel members. Spud wrench es used for assembling truss es and steel beams have tapered handles to use as drift pins.
