Nearly all animals come in two sexes, male and female. But sometimes, the lines can be blurred. Gynandromorphs are rare cases in which tissues of both male and female identity are found mixed in the same animal. This can happen through genetic aberrations whereby body cells lose sex-determining factors and adopt the opposite sexual identity. In species with an obvious sex difference in appearance, such as the morpho butterfly (Morpho menelaus didius), the results can be spectacular.

​Casi todos los animales tienen dos sexos, masculino y femenino. Pero a veces, las líneas pueden ser diversas. Los ginandromorfos son raros y los casos en los que los rasgos son masculinos y femeninos se encuentran mezclados en el mismo animal. Esto puede suceder a través de aberraciones genéticas mediante el cual las células del cuerpo pierden los factores que determinan el sexo y adoptan la identidad sexual opuesta. En especies con una diferencia obvia en el aspecto sexual, tales como la mariposa morfo (Morpho Menelao didius), los resultados pueden ser espectaculares.
