homozygosity

Presuming that your question is not that cryptic and you want a serious
answer, and presuming that by "silent" you mean third codon positions, then
you are asking for a selective pressure, at other than the protein level,
which demands homozygosity.

Your best bets here are stem-loop (fold) pressure, GC-pressure and
AG-pressure. These may act in combination to make a selectively very stable
monomorphism.

Sincerely,
Donald Forsdyke
