There are three general ways a cell can become specified for a particular fate; they are autonomous specification, conditional specification and syncytial specification. This type of specification results from cell-intrinsic properties; it gives rise to mosaic development. The cell-intrinsic properties arise from a cleavage of a cell with asymmetrically expressed maternal cytoplasmic determinants (proteins, small regulatory RNAs and mRNA). Thus, the fate of the ce… WebSpecification? •Autonomous Specification –Independent of other cells in embryo (self-differentiating parts) –Determined by internal cytoplasmic factors –If cleavage …
