Given a single sperm and a single egg, is there more than one resulting DNA combination they can form given the same human process of combining that genetic material. That is if I have the DNA off an egg sequenced and the DNA off a sperm sequenced, can I programmatically determine the DNA of the child formed by that egg and sperm?
Assuming we know the haplotype of the ovule and the haplotype of the spermatozoid, then the genotype of the future egg is perfectly deterministic. This is true to the extend that none of the following rare events occur:
- mitochondria could be inherited from the father as well
- mutations in the broad sense (see here for definitions) may occur outside an event of mitosis or meiosis
- The egg might pick up random sequence floating in the environment
Of course epigenetics elements might vary but this is another discussion.
