In extraordinary cause , some animals have each chromosome in very particular strong-arm neighborhood . run into the hermaphrodite — section of their bodies are virile … and the other parts are female .
The chromosome of an animal check its gender . But some animals have sex chromosome that are n’t expressed . Some have chromosomes that are verbalise internally , whereas a different set are expressed outwardly . Nature has many ways of combining genes , and some of these combinations show a distinctly binary way of looking at the creation . Such is the case with a genetical condition known as gynandromorphism .
Gynandromorphism is unknown in human , but it ’s sometimes expressed in fowl , crustaceans , arachnid , and insects . In insects , it ’s potential that this condition is caused when two sperm get into the orchis . One fuses with the lens nucleus and creates a female insect , the other continues on alone and create a male insect — both are at work in one body . In birds , gynandromorphism may be make by an inability of the sex chromosomes to branch when the newly - fertilize cell first splits in two .

epicene person can develop many different way . Some can be a patchwork of male and distaff body part — some birds even show virile and distaff sections of the same feathering . But bilateral gynandromorphism is something special .
In utter bilaterally symmetrical gynandromorphism , the animal ’s body is utterly dissever down the substance . One side is virile and the other side is distaff . butterfly have two different colored wings . Chickens have dissimilar plume on each side of the body . In some animals , such as louse , the size of each side of the consistency is markedly different .
This not only return clues on how androgyne break , but how bodies grow in worldwide . It seems that the first division of the fertilized cell could give wage increase to each side of an animate being ’s body . leftover is left and right is right , even from the showtime .
