[The Matrix] How do humans reproduce? If you have kids with someone in the matrix, do the machines outside have you both have kids outside too? In other word: Are your parents and children in the matrix your parents and kids outside of the Matrix? If so, how?

The short answer is maybe, but probably not.

The Machines are not running a nature preserve with the Matrix, it is a power source/processing bank. They are trying to be efficient. We know that women in the pods do not actually become pregnant and carry children to term. There is a whole "farm" that gestates babies for implantation into the Matrix. 

Now it is possible for the Machines to monitor the people's lives in the Matrix and find out who is trying to procreate, then harvest eggs and sperm from the individuals involved, bring them to the Farm and grow a baby. But that would be wildly inefficient. Most likely they just grow the babies from randomized sperm and eggs, and when they are ready to introduce a baby to the Matrix they just pick a sexual active woman, and run a program making her think she is pregnant. The baby has no real relation to the supposed mother or father, but they don't know that.

Now you may ask, well won't people know if their kids dont look like them? The answer is, that doesn't matter. The Machines tell elegant lies to keep the Matrix running, and the power of suggestion and the programming involved makes people believe that what is there in front of them is the truth. Remember, it is the rejection of the reality the the Machines present in the Matrix that causes people to seek out the truth, but very, very, few people are willing or even able to do that.

As for genetic testing, well there is a reason that the Matrix is meant to resemble the late 90s/early 2000s, there is still technological advancements, but not too much. Besides, the Machines can still tell people whatever they want, so even if for some reason a parent is unsure of their "child's" paternity, and goes through the trouble of trying to find out, the Machines still control all the "official" information handed out, they can tell the parents exactly what the Machines want them to hear.
