In 1929, Alfred Sturtevant studied mosaicism in Drosophila, a genus of fruit fly. [5] H. J. Muller in 1930 demonstrated that mosaicism in Drosophila is always associated with chromosomal rearrangements, and Schultz in 1936 showed that, in all cases studied, these rearrangements were associated with heterochromatic inert regions.

Mosaic authorship is the Judeo-Christian tradition that the Torah, the first five books of the Hebrew Bible/Old Testament, were dictated by God to Moses. [1] The tradition probably began with the legalistic code of the Book of Deuteronomy and was then gradually extended until Moses, as the central character, came to be regarded not just as the mediator of law but as author of both laws and ...

[1] Another definition is the "evolution of characters at various rates both within and between species".
