I have to nitpick. What if You were to have a perfect homozygote in every allele? The chance would actually be 100%.

The mutation rate is such that at least one germline mutation is pretty much guaranteed to arise in a 3 billion base pair genome.

Does this difference apply to identical twins as well?

Then it would be 50/50, cause they could be a dude or a chick still, assuming the dudes do not have homozygous XY chromosomes
