The word you want is distinguish or separate, stojam. To distinguish whose dna is whose in order to determine if the fetus has any abnormalities present.
Even so, such is an irrelevant concern. All it highlights is that it is wrong to think that a woman considers getting an abortion a light decision. It is most assuredly not. The woman has to consider her economic situation, whether she is mentally or physically ready for the issues that pregnancy brings about (including the possible arrival of a baby), or whether she wants her life to very suddenly be defined by the thing between her legs and what can issue forth from it.
Some women may choose to carry the pregnancy to term because they have a family willing to assist with child rearing and the obligations inherent to it are lessened sufficiently that the woman can pursue her vision in life.
But such is not at all a universal situation. Different women have different life situations, cultures, and priorities, and childbearing at that stage in their lives might not be the best thing for them. It might be too much of a strain upon the woman for any number of reasons that are of eminent importance to them.
You might disagree with their reasons, but it is neither your business or prerogative to do so.
A while back somebody said that a baby is a 'gift from god'. I will note the insult caused when somebody forces an unwanted 'gift' on another person. Just because one might think it a gift does not make it one for all.
