1. 50% of a child's genes come from both parents.
2. Divide exactly half of the DNA from the nucleus of the female/male cell to form the core material of the germ cell, 50% of which are randomly selected. Assuming that the gene of this hermaphrodite is AaBbCcDd.... until infinity, assuming N, then half of the randomly split may be all uppercase, all lowercase, and more likely mixed case, each combination has (1/ 2) The possibility of the Nth power, or the combination of 2 to the Nth power.
So here comes the question: randomly find two combinations from the combination of 2 to the Nth power, and the possibility of producing a complete fertilized egg species is 2 to the 2Nth power - how can we ensure that each self-reproduction is exactly the same? As for the gene that formed the original hermaphrodite, this possibility is only one of 2 to the 2N power, which is almost impossible.

Of course, from the perspective of time dimension, this small circle is inherently present. Therefore, it is possible that the fertilization happened to be one of the 2N powers of 2. There is no repetition, only that one time. It is just that some people understand and some people don't. Some people can pass through and most people can't.
