Detecting cardinal bird with half-male half-female body


At first we might think cardinal bird may be mutations cause the body was divided up into two different colors. But in fact, this is a case of sexual dimorphism with one side of the body is male and one is female side. This is a phenomenon very rare mutations in the animals, the scientific name is "Gynandromorphism".
Mutations bisexual Gynandromorphism are individual phenomenon with half the body is female and the other half are male, although they still grow and live normally. This particular phenomenon is discharged by a mutation in mitosis.
Normally a cell undergoing mitosis XY chromosomes duplicated to form XXYY. Then it was divided into two new cells XY. However sometimes the division process occurs suddenly makes it into a cell and a cell X XYY, prescribed two different sex. These cells continue the duplication and division makes a body with both chromosomes prescribed different sexes.
This phenomenon is often found in insects, especially butterflies, along with crustaceans such as shrimp and crab. However the discovery of it in a bird species is a rare thing.
The scientists also conducted monitoring special cardinal bird, they discovered that it was not mating with other birds regardless of any gender. Although it is still normal coexistence with the birds of the same species. Basically, both sexes have different effects on the body, so it is difficult for scientists to study what determines lifestyle and mating of these animals with this mutation.
Previously scientists have also discovered many individuals with mutations Gynandromorphism with half the body is male and half are female body:
Butterflies have half the body is male and half are female
