So, re-reading this:
After which, you will be required to select from the Matrix 23 individuals - 16 female, 7 male - to rebuild Zion.
It got me thinking - why exactly this ratio (and why exactly on that scale)?
Is it based on some out-of-universe scientific research for optimal seed population? Was there some in-universe explanation for the peculiar non-1-to-1 ratio?
I am fine with out-of-universe answers, but would prefer those backed by specific data (or in-universe answers based on canon material, or words from franchise workers), as opposed to pure unfounded guesses.
