Is it possible to get your parent's DNA by reverse-engineering your DNA

Since your DNA is a combination of your parents, that means if we take your DNA and remove the parts that belong to your mom, the leftovers would give us a pretty good idea of what your dad's DNA looks like. Does that mean it is theoretically possible to create a clone of your dad from those leftovers?

..I'm going to say no on this one. If what I'm understanding is right, you want to take a strand of your DNA, rip out the pieces that belonged to your mother, and assume that everything else belongs to your father...which...I don't think would work.

Human DNA, despite all our differences phenotypically, is actually pretty conserved. Much of it is the same between individuals. What differs is the allele that each person carries, and because appearances can be affected by a number of different genes, I'm not sure that picking out the alleles that you know belong to your mother would work.

For example, you mom has blond hair, and you have blond hair. So you pull out the allele for blondeness. Then what color hair did your father have? Blonde? Brown? Red? Black? There isn't really a good way of knowing. (and if someone feels like arguing with me about recessive dominant traits, I'll argue back that your father could easily have been either a blonde or a brunette and still passed on the gene to make you blonde too.)

Hope that helps!

Unfortunately, in this case, I don't think that it will really work. As the other poster mentioned, you cannot take out various attributes from the gene codes that you have to seperate them from your mother or father. It still may be possible if you get a geneticist to look at both of your parents genetics as well as yours. That would be the only way possible.
