Gynandromorphism is a biological phenomenon where an organism exhibits both male and female characteristics. This condition can occur in various species, including insects, birds, and crustaceans. Gynandromorphs may display distinct physical traits, such as coloration or body structure, that are typically associated with each sex. The cause of gynandromorphism is often linked to genetic anomalies during early development, such as errors in cell division. In some cases, it can result from the fusion of two embryos, one male and one female. Researchers study gynandromorphism to better understand sexual differentiation and genetic expression in living organisms.
