In theory, if you have enough kids, would they start genetically repeating?

Question

If you get 50% of dna from each parent, and there’s a finite amount of dna in each one, in theory, if you had enough kids (an impossibly large quantity) would your kids eventually be genetically identical to previous kids? Would the possible number of dna combination end eventually?

Answer 1

Due to meiosis, the process by which gametes (sex cells – sperm and ova) form;

there is a 1 in 8388608 chance of getting the right sperm

1 in 8388608 chance of getting the right ovum

Multiplying these together gives a 1 in 70368744177664 chance of YOU being created (genetically as you rather than a sibling), so you’d need to have a lot of kids to be likely to get repetition.
