>>13371938It would theoretically be possible to produce a child in such a way, but it would be extremely unlikely for such a thing to occur, but let's say you want to clone yourself.
The odds of cloning yourself would be 1 in 1,388,608, due to the human genome being diploid.
To explain more fully; your genome consists of 23 pairs of chromosomes (46 in total).
When you reproduce you pass on just one of each of these pairs of chromosomes to your offspring, and the other comes from the other parent.
So let's look at your genome and the genome of your identical clone (of the opposite gender) with whom you wish to produce a clone child.
We'll ignore the difficulty of the sex chromosomes for the moment and just look at chromosome 1.
You have two copies of chromosome 1 in your genome, which we will call A and B, giving you the genotype AB.
Your opposite gender clone also has the genotype AB.
When the two of you breed you produce a simple punnet square of possible outcomes:
An A from you and an A from your clone produces a child with genotype AA.
An A from you and a B from your clone produces a child with genotype AB.
A B from you and an A from your clone produces a child with genotype AB.
A B from you and a B from your clone producess a child with genotype BB.
Put more simply you would produce a child with the same AB genotype as yourself only half the time (ignoring the very rare chance of trisomy occuring).
These odds would then have to be repeated for every one of the 23 chromosome pairs in your genome, making the odds of you producing a clone of yourself by mating with yourself 1 in 2^23 = 1 in 1,388,608.
