Below is a hypothetical developmental pathway. this pathway leads to the expression of a black pigment in certain cells of the ectoderm (the spot cells) which results in the ladybug's spotted appearance. cells of the ectoderm where black pigment is not produced are red.
l | d → y | b → black
based on the pathway above, will the spot cells in ladybug mutant lacking the d gene be able to make black pigment?
