Describe the positional value of the developing eye in the fruit fly
In the synthesis of the fruit fly eye what is the interaction between photoreceptors known to switch on?
What does the ectoderm form?
What does the mesoderm form?
What does the endoderm form?
What is the site of secretion of shh?
What happens if BMP is present?
