Regarding the genetic transmission of anxiety and depression, even happiness (narrowly defined) is now said in the popular media to have a 50% genetic component, so I find it all very confusing.I'm a female who used to suffer from depression and currently suffers from anxiety. I'm considering not having biological children.
Regarding other factors as well:Anxiety Disorders
Lifetime prevalence for any anxiety disorder: 15-25%
Heritability estimated at about 40%
Major Depressive/Unipolar Disorder
Community samples provide lifetime risk of 10-25% for women and 5-12% for men
Heritability: Unclear (~20-80%); meta-analysis reports 31-42%
Empiric Risk Data
A study of adopted children, published in the American Journal of Psychiatry in September 2008, found a significantly higher risk of adolescent depression if the adoptive mother had major depression. Depression in the adoptive father, however, was not associated with increased risk of adolescent depression.

A larger, more important point may be your own happiness. For example, depending on how one measures or defines happiness:Increased rates of anxiety in the children were found only when their mothers met three specific diagnostic criteria - considerable impairment in daily life; onset of anxiety before the age of 20; and at least 2 anxiety disorders. Thus only severe maternal anxiety disorder is associated with an increased rate of anxiety disorders in children.

having children “has only a small effect on happiness, and it is a negative one”

By the way, a new article:Help me weight out the pros and cons.
"If things get too overwhelming, I just schedule myself a dentist appointment," writes Laura Bennett in Didn't I Feed You Yesterday: A Mother's Guide to Sanity in Stilettos. "There is nothing like a root canal to secure some guilt-free me time. One medicated hour in the chair with no disturbances can be pure bliss, and as a special bonus, I get to leave with a Vicodin prescription."

Similarly, Einstein did not have schizophrenia, but he passed such genes onto his son:Vulnberability to anxiety or depression is in part genetically transmitted, whether or not the parent(s) show active symptoms.
On the other hand, that vulnerability is not all bad - it is associated with some positive traits as well.
