Allele

Compact 2D textbook-style genetics diagram or standalone icon representing a single allele as a variant form of a gene. It may be shown as either a short DNA or double-helix fragment, twisted ladder section, labeled DNA block, capsule-like gene marker, or as a small highlighted band, dot, marked segment, or labeled locus at one fixed position on a chromosome arm. The allele has a clearly defined compact shape and is visually distinguished from alternate versions by a different fill color, color-coded sequence block, paired colored base rungs, pattern, or small label, while preserving the same overall position or shape as another gene copy. Clean, simple, diagrammatic rendering with the surrounding chromosome or DNA shown in neutral contrasting color if included.
