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?
- 1If the AB and P 1 blastomeres are experimentally separated, the AB cell will generate all cells it would normally make.
- 2When AB divides to form daughter cells, ABp becomes different from ABa through its interaction with the P 2 cell.✓
- 3The specification of the AB cell is determined by the presence of cytoplasmic determinants.
- 4The P 2 cell produces a morphogen for the determination of the ABp cell.
Correct answer
When AB divides to form daughter cells, ABp becomes different from ABa through its interaction with the P 2 cell.
