Are there identical children with different birth dates?
There are identical twins who were born on the same day.
Can there be the same children with different birthdays, for example two years apart?
During sexual intercourse there is also a lot of sperm where only one can reach the egg.
If the same parents have sex on any other day, would there be a lot of sperm every day where the child looks exactly like them?
So if my parents, for example, had 3 other children together, would it have been possible for the other 3 children to have looked exactly like me?
There are up to 200 million sperm, maybe it is like this:
- 100 million male + 100 million female sperm.
- 10 million sperm look exactly like person A
- 10 million sperm look exactly like person B
- 10 million sperm look exactly like Person C
etc., in the example there would be 10 appearance variants for male children and 10 variants for female children.
What do you think? What are your experiences? Do you have siblings who look identical, for example, who also look exactly like you?

Yeah, I can. In the case of so-called secondary twin births, this is possible if the twins are monocygotic (unique). It may be that a twin comes to the world prematurely as an early bird because of complications. Medically, the birth of the second child is prevented until the calculated date of birth is reached. Between births there are not several years, but only a few weeks to a few months.
Theoretically, it is also possible for a mother to receive one-of-a-kind twins at New Year’s Eve, which is a child shortly before midnight at 31st. December, the other shortly after midnight on 1 January. In this case, not only birthdays would be different, but also birth years.
The fact that two non-monocygotic children are purely randomly genetically identical is practically excluded.
Our genome has 3-4 billion base pairs. Many millions of them are variable. Two randomly selected people still differ in four million base pairs. In the case of siblings it will be even less different, but identical or almost identical people who are not twins would be a big coincidence. As if two books were coming to the market in a short time, written by different authors, but contain the same story.
Because children do not arise from sperm alone, normal fertilization cannot occur 2 years later to a randomly genetically identical sibling.
Apparently, it hasn’t happened yet, with almost 8 billion people on the planet. Otherwise we would have found out in the picture. The science magazine I would recommend. You can learn.
It could be as follows:
When the fertilized egg splits, only in 2 then into 4 cells, these cells are still so that from each of them a human can become. So if I take an egg in the early stage of division and separate the four cells from each other, then I can plant them in a woman at other times.
I can freeze the other three. (or stimulate new to division, and then separate again) I can take one of the frozen cells after two years and then let them be discharged.
And another two years. And so on.
This already works with today’s means at higher mammals.
But is forbidden in people. I’m fine. Afterward, some dictator comes up with the idea of creating a cloning arm. Where probably the prohibitions do not contribute to the fact that this is not done, rather the costs. And meaninglessness. Because in a cloning arm, the enemy only has to find out where the model is the weak point, and then knows it for everyone.
This is theoretically possible.
But the likelihood is against NULL.

No, that’s absolutely impossible.
Yes, siblings can look very similar even if they do not escape the same pregnancy. But they are not twins.
Your remaining theories are nonsense.
