Wait how do they sequence the DNA before cell replication? There's only 1 copy of the genes at that point right? Is it scam or am I :marseybrainlet:

They are using frozen embryos which are a few days old and only need a few cells to act as a representative for the rest of the embryo. At the time of the embryo creation, both copies of each gene are already present (we get one from each parent) because the egg (with one copy of each gene) has already met the sperm (the other copy). :)

They implant day 3 or so embryos that have hundreds of cells.
