[Alien:Covenant] [no spoilers] What was the plans/deal with the Embryos on the colony ship.

The ship contained like two thousand colonists but also a thousand "second generation" colonists that were frozen embryos. But who's Embryos? Are they pre-fertilized members of the crews children screened for imperfections to be re-impregnated into their respective mothers? Are they other peoples kids to add genetic diversity to the founding population and lessen inbreeding? 

If this is not the right place to ask this question please tell me somewhere else to ask.

Most likely other people's. AFAIK, the number of people needed to avoide inbreeding problems is around ~120, if you do the math right. But a few thousand allows for people to have a meaningful degree of actual choice in their partners.
