A genomic fragment containing eya (the same fragment as present in eya+tGR), from which the "IAM" enhancer region (an approximately 3kb fragment) has been deleted.
eyaGRΔIAM rescues the lethality of eyacli-IID/Df(2L)BSC354. The rescued adults have markedly smaller eyes than normal and lack ocelli. The eyes have a normal complement of rhabdomeres.
