Post #1 family relationships

I was reading the book and on page 46 it talks about how the family that a person grew up with can really affect the way they interact with there spouse. I had some sort of idea that this is what happened but not the extent that "...poor marital and parent-child relationships predict lower quality and stability in the offspring's long-term intimate relationships." This brought me to the thought that what if someones great-great grandparents didn't have a top-notch relationship with there parents; would the great-great grandchild have a hard time with there parents? Does it pass down to that extent?
