“Sci fi plot alert”: what happens if due to random chance/genetic drift the “A” version of the X chromosome becomes more common and the last male dies? This would be more probable the smaller the population is. And, I dunno, a space rock snipes the sperm storage freezer. (similar to what happened in Seveneves)
When the space ship lands there is a 1% chance that no males are among the first 16 births (3416)
Luckily males are firtile for longer so if the second generation had no men the first generation still works
If the A had a mutation such that AX did not have 50% chance of passing on a A, then the gender ratio would be even more extreme, if the last man dies the a AY female could probably artificially incriminate a female.
You can update the matrix and do the for product to see how those different rules pan out, if you have a specific ratio you want to try then I can calculate it for you, calculating a target gender ratio will require a mathematician as this is a Markov process and their Transmission Matrix are hard to calculate fom a target steady state, if you are a for mortal like me
