In Caenorhabditis elegans, blastomere identity occurs both through conditional and autonomous modes of cell specification. Which one of the following options is a correct statement in this regard?
1
If the AB and P1 blastomeres are experimentally separated, the AB cell will generate all cells it would normally make.
2
When AB divides to form daughter cells, ABp becomes different from ABa through its interaction with the P2 cell.
3
The specification of AB cell is determined by the presence of cytoplasmic determinants.
4
The P2 cell produces a morphogen for the determination of the ABp cell.
