In studies of gene expression,which observation would be the least likely?
A) As the result of radically different developmental processes within an insect species,some members of the species have a pair of wings that its conspecifics lack.
B) Expression of a gene that is important in developmental processes varies with temperature.
C) A species of fish is much larger than fish in a closely related species because a gene affecting bone growth is expressed earlier in development in the larger fish than in the related species.
D) The amino acid sequence of a Hox gene protein is extremely similar in nematodes and humans.
E) One rodent species has a narrower face than all others,because in that species the expression pattern of a gene that is important in development is more restricted in its spatial effects.

Radically different developmental processes leading to some members of an insect species having a pair of wings that others lack is highly unlikely, as such drastic differences are typically not observed within a single species.
