On a person's detail page who has both adoptive and biological parents, both sets of parents will always show like this view from the beta site:
The Preferred parents, as marked at the top of their couple box, is the set of parents that show on pedigree views. The is set using the Set Preferred link just under the Show All Family Members slider.
In the Landscape pedigree view, you can switch which parents show by clicking on the small arrow in front of the parent box:
For the other pedigree views you do need to go to the detail page, switch the preferred parents, then return to the pedigree chart.4
