In brief: "50% solution"
A pregnant(not surrogate) mother contributes 50% of the chromosomes to her fetus.

In brief: Not sure of question
Are you referring to the fetal DNA test in maternal blood for Down syndrome and other trisomies? If so, that testing is specific for fetal DNA, not maternal DNA, so a mother could not influence the results, which are 99% accurate.
