Gynandromorphism - Wikipedia Gynandromorphism is the phenomenon that occurs when an individual organism possesses both male and female phenotypes due to genetic chimera of sex chromosomes in cells across the body and is most easily recognized in species that display sexual dimorphism [1]
Gynandromorphism | Natural History Magazine Gynandromorphs (“gyne” from Greek meaning female, “andro” for male, and “morph” meaning variety) are individual animals that have both genetically male and female tissues and often have observable male and female characteristics
This ‘Extremely Rare’ Bird Is Half Female, Half Male Gynandromorphism could occur if a bird produced a single egg with two nuclei—one with a Z and one with a W chromosome—that becomes “double fertilized” by two sperm with Z chromosomes
The Mysterious Gynandromorph - JSTOR Daily Gynandromorphy is an extremely rare condition observed in a variety of insects, snakes, crustaceans, and birds Given how hard gynandromorphy is to detect, it may be more common than we realize Gynandromorphy can manifest in at least three forms, according to biologist Janice L Krumm in the Journal of Crustacean Biology
Descriptive versus causal morphology: gynandromorphism and . . . In animal species with separate sexes, abnormal individuals with a mix of phenotypically male and phenotypically female body parts are generally indicated as gynandromorphs, whereas individuals with intermediate sexual phenotypic traits are generally indicated as intersexes
How gynandromorphs manage to be half male and half female Unlike insects such as lepidopterans, the arrangement of their sex chromosomes mirrors that of mammals: females have XX chromosomes and males have XY chromosomes Incidences of gynandromorphism in these flies were among those first described in the early 20th century
