History of Development of the Fluid Mosaic Model

Q. Human and mouse cells are treated with red and green fluorescent dyes respectively and are made to fuse. The resultant cells are kept at ${37}^{o}C$. Assuming that R and G represents the localisation of red and green dye respectively, the probable distribution of dye on the surface of the cells will be
