Reminds me of the CS problem: write a program which prints out its own source code.

But way more impressive. How can a cell with a single strand of DNA 'decide' which copy of a gene is a mutation? Or do eggs just bias for sperm with more genetic differences?

These decisions interface via binding sites[1] which can be thought of as having "bias".

If I understand correctly, they see associations of alleles in the zygotes that suggest the gametes have not paired randomly.

Basically it could be that the egg and the sperm have different proteins expressed on their cellular surfaces which go together like a lock and key and may also function as attractors ( chemical sensing or something).. all of this would originate from genes in the gametes.
