If you are not a Grimm you do not have Grimm blood. Mama Kelly pointed out that Uncle George was not a Grimm yet he had the same family as her brother.

Based on the show wesen type in nature is based on the  dominant strain except for biests. Biests are like spirits that affected your blood and once you lose them you are "human" again. Biests in a child are different if both parents had one vs one parent had one.

A child can have a different blood types than both parents and have DNA from both so your DNA theory does not work with humans either.

According to  Rosalee  and  Monroe,  if the two parents are Wesen but of different types, then the offspring will be considered a Vorherrscher ( FOHR-hair-shuh ; Ger. "prevalence"), with the dominant strain's biological characteristics being more prominent; however, there is a small risk of health issues. ("Stories We Tell Our Young").
