You may remember this Batman villain who appeared to be split in two. His name was “Two Faces”. What would you think if we told you that there is more than one in nature who could be this villain? Not because of a terrible accident, come on. But because of the bilateral gynandromorphy. A strange evil among which the bird, which is male and female at the same time, was found by scientists in Pennsylvania.
It is divided in half. One side has yellow wing tips. The other side has a pink underside. Is a fat pico from pink breastPheucticus ludovicianus). He appears to have a genetic abnormality known as bilateral gynandromorphism. It has been seen in birds before.
It’s not like hermaphroditism. They don’t have both reproductive organs (male and female). Gynandromorphs show different sexual characteristics on each side. The bird, which is male and female at the same time, appears to have been cut in half and glued back together. On the tail, one side has a brown side and the other has a black side. This division could even affect your brain.
The program director is Annie Lindsay. He said his team was in awe. “One of them described it as seeing a unicorn.” This strange phenomenon has also been observed in reptiles, butterflies and crustaceans. It was believed that gynandromorphs formed from the fusion of two developing embryos. There is another theory.
If two sperm fertilize an egg with two nuclei instead of one, they could divide separately. Each side of the offspring’s body could theoretically have its own gender.
“We wonder if it is reproducible,” wrote PARC researchers in a press release. “Usually only the left ovary works in birds. The left side of this bird is the female side. In theory, if it mates successfully with a male, it could produce young. Other half-sided birds with female parts on the right are often sterile.
Even so, this beautiful bird may not be able to mate. Bigbills are songbirds, and men rely on their music to attract women. It is unclear whether this bird can attract a partner if its song confuses other birds. Did someone say neutered?
Some gynandromorph zebra finches can sing a male song around a female. However, this does not apply to everyone. In 2017 an Eastern Towhee became gynandromorphic (Pipilo Erythrophthalmus). She sang and fed her young, suggesting that in some cases offspring are possible.
The duality of all being is not only expressed in comics like Batman. It is also in nature.
