I. (noun)
Sense 1
Meaning:
(genetics) the process of locating genes on a chromosome
Synonyms:
Classified under:
Nouns denoting acts or actions
Hypernyms ("mapping" is a kind of...):
procedure; process (a particular course of action intended to achieve a result)
Domain category:
genetic science; genetics (the branch of biology that studies heredity and variation in organisms)
Derivation:
map (locate within a specific region of a chromosome in relation to known DNA or gene sequences)
Sense 2
Meaning:
(mathematics) a mathematical relation such that each element of a given set (the domain of the function) is associated with an element of another set (the range of the function)
Synonyms:

Hypernyms ("mapping" is a kind of...):
mathematical relation (a relation between mathematical expressions (such as equality or inequality))
Domain category:
math; mathematics; maths (a science (or group of related sciences) dealing with the logic of quantity and shape and arrangement)
Hyponyms (each of the following is a kind of "mapping"):
multinomial; polynomial (a mathematical function that is the sum of a number of terms)
expansion (a function expressed as a sum or product of terms)
inverse function (a function obtained by expressing the dependent variable of one function as the independent variable of another; f and g are inverse functions if f(x)=y and g(y)=x)
Kronecker delta (a function of two variables i and j that equals 1 when i=j and equals 0 otherwise)
metric; metric function (a function of a topological space that gives, for any two points in the space, a value equal to the distance between them)
transformation ((mathematics) a function that changes the position or direction of the axes of a coordinate system)
isometry (a one-to-one mapping of one metric space into another metric space that preserves the distances between each pair of points)
operator ((mathematics) a symbol or function representing a mathematical operation)
circular function; trigonometric function (function of an angle expressed as a ratio of the length of the sides of right-angled triangle containing the angle)
threshold function (a function that takes the value 1 if a specified function of the arguments exceeds a given threshold and 0 otherwise)
exponential; exponential function (a function in which an independent variable appears as an exponent)
Derivation:
map (to establish a mapping (of mathematical elements or sets))
II. (verb)
Sense 1
-ing form of the verb map
