One 72 years old retired man in England recently found a half-red-half-green apple on an apple tree of his own garden, and this apple was just divided by a central line . The old man supposed it was a trick made by someone, but when he approached the tree, he was shocked that the magical effect formed naturally . Experts pointed out that the probability of the occurrence of this phenomenon is one in a million .
This peculiar phenomenon is caused by genetic mutation during apple's growth, and the genetic mutation is related to getting different time's sunlight . Generally speaking, the red half will taste sweeter than the green half .
