C. elegans embryo uses both autonomous and conditional modes of specification.
Conditional specification at the 4-cell stage can be seen in the development of
the endoderm cell lineage and also in the establishment of dorsal-ventral axis.
Following are few statements regarding this figure:
A.
If the P2 cell is removed at the early 4-cell stage, the EMS cell will divide
into two MS cells and endoderm will be made.
B.
In pop-1 deficient embryos, both EMS daughter cells become MS cells.
C.
When the position of ABa and ABp was reversed, their fates get reversed and no
normal embryo forms.
D.
In embryos whose mother have mutant glp-1, ABp is transformed into ABa cell.
Which of the above statements are true?
