Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Genetic mosaicism is the presence, within a single organism grown from one fertilised egg, of two or more populations of cells that differ in their genotype, arising when a mutation occurs in a cell after fertilisation and is inherited only by that cell's descendants. It is set apart from chimerism, where the differing cell lines instead come from more than one fertilised egg fused together. Biesecker and Spinner's 2013 A genomic view of mosaicism and human disease reviewed how such changes after conception arise and cause disease. The referent is a mixture of cell lineages inside one body, not an artwork of stone fragments, a landscape of habitat patches, or a picture of membrane structure.[1]
In landscape ecology a mosaic is the patchwork formed by the different habitat patches, connecting corridors, and background matrix that make up a stretch of land, treated as one spatial pattern whose arrangement shapes how organisms, water, and energy move through it. Forman's 1995 Some general principles of landscape and regional ecology set out the patch-corridor-matrix model by which such a pattern is described. The referent is the spatial arrangement of land cover across a region, read from above as a map, not a wall of stone tesserae, a body of mixed cell lines, or an account of how a membrane is built.[2]
The fluid mosaic model describes the cell membrane as a two-dimensional fluid in which proteins float within and across a lipid bilayer, so that the membrane's parts form a mixed, movable arrangement rather than a fixed layered sheet. Singer and Nicolson's 1972 The fluid mosaic model of the structure of cell membranes proposed this arrangement and made it the standard picture of how a membrane is organised. Here the word names a scientific model of one membrane's structure, not a stone artwork, a body of mixed cell genotypes, or a patchwork of habitats across a landscape.[3]
