In biology, an identification key, taxonomic key, or frequently just key, is a printed or computer-aided device that aids in the identification of biological organisms. Historically, the most common type of identification key is the dichotomous key, a type of single-access key which offers a fixed sequence of identification steps, each with two ...
Single-access key. In phylogenetics, a single-access key (also called dichotomous key, sequential key, analytical key, [1] or pathway key) is an identification key where the sequence and structure of identification steps is fixed by the author of the key. At each point in the decision process, multiple alternatives are offered, each leading to ...
A dichotomy / daɪˈkɒtəmi / is a partition of a whole (or a set) into two parts (subsets). In other words, this couple of parts must be. mutually exclusive: nothing can belong simultaneously to both parts. If there is a concept A, and it is split into parts B and not-B, then the parts form a dichotomy: they are mutually exclusive, since no ...
The analytical profile index, or API, is a classification system for bacteria based on biochemical tests. The system was developed to accelerate the speed of identifying clinically relevant bacteria. It can only be used to identify known species from an index. [1] The data obtained are phenotypic traits. DNA sequence -based methods, including ...

Bergey's Manual Trust was established in 1936 to sustain the publication of Bergey's Manual of Determinative Bacteriology and supplementary reference works. The Trust also recognizes individuals who have made outstanding contributions to bacterial taxonomy by presentation of the Bergey Award and Bergey Medal, jointly supported by funds from the Trust and from Springer, the publishers of the ...
Dummy variable (statistics) In regression analysis, a dummy variable (also known as indicator variable or just dummy) is one that takes a binary value (0 or 1) to indicate the absence or presence of some categorical effect that may be expected to shift the outcome. [1] For example, if we were studying the relationship between biological sex and ...
In linguistics, a yes–no question, also known as a binary question, a polar question, or a general question, [1] is a question whose expected answer is one of two choices, one that provides an affirmative answer to the question versus one that provides a negative answer to the question. Typically, in English, the choices are either "yes" or ...
