Heredity is the transferrence of traits from parents to their children. You get your traits, like your eye color, your height, your physical characteristics, predisposition to disease, even much of your personality, etc. from the DNA that you inherited from your parents. DNA in your chromosomes contain genes, which encode the proteins that make up your body and those that tell your body how to regulate those proteins in space and time. Each of your parents contributed 1/2 of your DNA -- 23 chromosomes each through a process called meiosis to produce a sperm and egg. When fused together, they then make the 46 chromosomes which make up the total human chromosome complement. Without DNA, there would be no heredity. You couldn't pass on anything to the next generation. It would be like running your computer without any operating system or any software.

It is like comparing a live concert (heredity) and the music sheets(DNA). The music score gives a basic definition of what is to be played, but a lot depends on other factors, conductor's interpretation, players, acoustics, the audience, etc.
Take acoustics for examples. Beethoven's 5'th (especially the BAM, BAM, BAM part) will not manifest itself in a room with bad low frequency acoustics, and there is nothing you can do in the score to fix it. You will only inherit certain traits "written in your DNA" if chance and physical and nurture conditions prevail.

when you are being created in the womb, you get chromosomes from each of the parents.
Chromosomes contain DNA.
DNA is the "code centre" where they decide what proteins to produce in the body and where is goes.
you receive DNA from each of the parents
So, your body will produce the proteins that will give the characteristics of the parents.
However, because the DNA are mixed, there will also be results of characteristics that are not present in the parents.
Blood group is hereditery.
Parents who have blood group A and B, can have a child whose blood group is O.
this is due to the gene for the O group being recessive.
Search around on the web. I believe there are alot of info that goes into further details.

heredity are traits passed on from parent to child.
dna is the way these traits are passed on.
dna contains genes which is the basis for the traits we see in people.
