If two people have add, what is the likelihood of their child having it?

In brief: Increased risk

Add, or adhd (attention deficit hyperactivity disorder) is not attributable to a single gene like, say, eye color is.
Rather it's a multigene issue, plus likely requiring environmental input or trigger to bring it out. So calculating the likelihood of inheriting adhd from 2 parents is rather imprecise, but, we can conclude that it is a substantial risk compared to neither parent having it.

In brief: Much higher

Than if neither parent had it! the heritability of adhd is about 80%, while the heritability of height is about 90%.
