Figure 1. Genetic assimilation of crossveinless phenocopy and epigenetic assimilation of the ELBO phenotype.
a) Shown are a crossveinless wing and a wild-type wing (modified from [16]).
b) An eye containing an ectopic large bristle outgrowth (ELBO) in one eye and no outgrowth in the other eye in a KrIf-1/+ adult fly [14].
c) Genetic assimilation of the crossveinless phenotype (circles; data from [16]) and epigenetic assimilation of the ELBO phenotype (data from [14] for generations 2–13 and unpublished for generations 14–22).
