Morphology of a male skeleton shrimp, Caprella mutica Morphology in biology is the study of the form and structure of organisms and their specific structural features. [1]This includes aspects of the outward appearance (shape, structure, color, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of internal parts like bones and organs, i.e. internal ...
When the stroke is part of a lowercase [4] and rises above the height of an x (the x height), it is known as an ascender. [7] Letters with ascenders are b d f h k l . A stroke which drops below the baseline is a descender . [ 7 ]
In genetics, the phenotype (from Ancient Greek φαίνω (phaínō) 'to appear, show' and τύπος (túpos) 'mark, type') is the set of observable characteristics or traits of an organism. [ 1 ] [ 2 ] The term covers the organism's morphology (physical form and structure), its developmental processes, its biochemical and physiological ...
A cladogram (from Greek clados "branch" and gramma "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be ...
In phylogenetics, a plesiomorphy ("near form") and symplesiomorphy are synonyms for an ancestral character shared by all members of a clade, which does not distinguish the clade from other clades. Plesiomorphy, symplesiomorphy, apomorphy, and synapomorphy all mean a trait shared between species because they share an ancestral species. [a]
A glyph (/ ɡ l ɪ f / GLIF) is any kind of purposeful mark.In typography, a glyph is "the specific shape, design, or representation of a character". [1] It is a particular graphical representation, in a particular typeface, of an element of written language.
So the concept can be understood as well in terms of "a character newer than" (autapomorphy) and "a character older than" (plesiomorphy) the apomorphy: mammary glands are evolutionarily newer than vertebral column, so mammary glands are an autapomorphy if vertebral column is an apomorphy, but if mammary glands are the apomorphy being considered ...
In typography, the body height or point size refers to the height of the space in which a glyph is defined. The metal sort: b is the body or shank, c is the body height or font size. Originally, in metal typesetting, the body height or the font (or point) size was defined by the height of the lead cuboid on which the actual font face is moulded.
