yes and no.
(I know helpful eh?)
Sometimes behaviour is trained, sometimes it is ingrained.
A baby who is spooky as a youngster may settle into a calm quiet adult.
A baby who is calm as a baby most often stays that way.
I tend to hold back calmer rabbits...but rabbits that aren't so calm that they are boring. I want a rabbit who can make me laugh, but doesn't make a body have to say "CHILL OUT, I just WALKED into the rabbitry!"... But I want some rabbits that do react to changes in their environment, and rabbits are active in their cages (those sit in the corner very quiet does I just find boring)... and having the odd "spook" rabbit can be very helpful as they will alert you to something odd going and help you pay closer attention....it also means having the odd boring rabbit isn't a bad thing either.
you have to weigh it out right?
Is the spookiness over the top or is it where it needs to be?
BUT back to your question.. can it be inherited?
YES (and no).. spooky rabbits tend to beget spooky rabbits, but you need to know what causes it. is to too much WILD rabbit in them that would keep them safe in the wild. OR is it poor handling?
Sometimes it skips a generation so spooky rabbit always has quiet kits, but then quiet kit matures and produces kits with a highly developed startle reflex...
It's a hard one to figure out sometimes.
