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?

Without D gene, Y will not be produced and hence B gene is not inhibited and will produce the black pigment thus the statement is false
