is BPD genetically transferred?

[Before you can make things better, you have to stop making them worse...]

My ex has a daughter who I worry about because based upon what little research I've done there can be somewhat of a genetic component.  She is a teenage and already suffers from depression and anxiety.  The poor child has been victim to her dads bizarre behavior and rages.  I think it would be awful if she has to deal with the disorder herself. 

Does anyone have more insight into this issue?

As far as i know yes, although it doesnt mean all offspring will have it.

The way i see it, and this is just me guessing, im no expert. Is that some peoples genetics are more susceptible to getting it than others, but there still needs to be some sort of trauma or abandoment growing up for the person to 'become' BPD.

I have two children with my uBPDexw and I see the signs of the disorder in my S. He has been difficult since he was a toddler. Constant fits along with not recognizing boundaries and has never listened.

(The not listening appears to be something that is a norm in my exw's family as they all complain to each other that they never listen to one another)

My son would never stay in timeout when scolded as a baby and it seems to be ingrained in him now to dysregulate over the smallest things. His mother has always treated him like he was an adult and was never consistent in the parenting of timeouts or punishments. Some of it may also be conditioning but the genetic component appears to be there. My daughter will listen and will stay in timeout for me but not my exw and she is very different from my son. She is however learning and displaying behaviors in imitation of my son but I am hoping for the best.

I read about this study a little while ago:

The researchers conducted a genetic linkage analysis of the families and identified chromosomal regions that could contain genes that influence the development of BPD. Trull found the strongest evidence for a genetic influence on BPD features on chromosome nine.

And from a previous study also mentioned in the same article:

The research team found that 42 percent of variation in BPD features was attributable to genetic influences and 58 percent was attributable to environmental influences

So almost half nature and half nurture.

50/50 odds... .  not sure if that's good or not.  so if you have both genetic influences and some environmental influences as well, you not in a good place... .
