Insect

Caption

An insect in the fourth nymphal stage of development (Figure A) progresses normally to the fifth development stage (Figure B). However, if a gene called broad is suppressed in the first half of the fourth stage, the nymph moves to the fifth stage but keeps pigmentation patterns and other characteristics of the fourth stage (Figure C).
