Divorce has been found to be heritable: if one or more of your close relatives has been divorced, you are more likely to get divorced than if none of your relatives have been divorced. What does this imply about the causes of divorce

That one or more genetically influenced traits are relevant to divorce.

Explanation:

Heritability is estimated by comparing individual phenotypic variation among related individuals in a population. Heritability is an important concept in quantitative genetics, particularly in selective breeding and behavior genetics (for instance, twin studies). It is the source of much confusion due to the fact that its technical definition is different from its commonly-understood folk definition. Therefore, its use conveys the incorrect impression that behavioral traits are "inherited" or specifically passed down through the genes. Behavioral geneticists also conduct heritability analyses based on the assumption that genes and environments contribute in a separate, additive manner to behavioral traits.

That one or more genetically influenced traits are relevant to divorce

Explanation:

This means that parent Gene's can influence divorce in their children because it is the genetic influence with personality traits that influence divorce. Divorce is prompt or likely to happen if the parent are divorced example if we look at the rate of divorce and we conduct a background check on most divorce couple we are likely to find out that either of their parent are divorce than if none of their parent or relatives have been divorced.

Therefore divorce can influence the personality trait or behaviour of a person through their parents although not in all cases which is why one or more genetically influenced traits are relevant to divorce.
