Mutations affecting eyespot morphology in Bicyclus anynana butterflies shed light on the developmental basis of novel traits
Eyespot morphology in Bicyclus anynana is affected by mutations in a locus that is also important for embryonic segment polarity, and is thought to encode a negative regulator of Wingless signalling that may play an important part in the evolution of novel traits. Three different mutations in this locus lead to different eyespot size and/or color phenotypes. The butterfly depicted in the present image carries a mutation that leads to greatly enlarged eyespots.
