Mosaic development and regulative development

WebDuring the mosaic development, the future embryo contains all the distinct cytoplasmic determinants that are distributed in distinct cells. Regions of the organism differentiate very quickly if each cell contains specific cytoplasmic determinants since the first divisions : then the cell divides to give all the other cell of its type, and the same process happens in all … WebRegulative vs. mosaic development.
