The figure above represents a late zebrafish gastrula. The following concepts may be proposed during further development of the embryo.
A. The concentration of FGF decreases from the yolk towards the epidermis, along with the increase of BMP activity from the dorsal to the ventral axis.
B. Increase in FGF activity in the epidermis with concomitant decrease in BMP activity towards the ventral axis.
C. Neural induction in zebrafish is independent of the organizer and depends on activation of BMP signalling.
D. In comparison, both Xenopus and chick embryos require activation of FGF for neural induction to occur in addition to BMP inhibition.
Which of the above statements are incorrect?
