@timbo5lice your explanation is good, but it is not 'human gene structure', it is just DNA
DNA contains 2 strands and genes are the regions on stand that code for protein 
Gene structure is totally different thing, and its same for all humans. 
@kaetlyn.2 a hereditary diseases is a genetic diseases, it passes down to next generations because when male and female make gametes/sex cells - they pass on information to gametes, and then when fertilization occurs, gamete cells fuse together and their genetic material from each parent too fuses together and zygote is formed 
thats why the baby has similar genetic material to their parents. 
but concept of genetic disease passing from parent to kid is a bit more complicated that you might think it is. If you need a more advanced answer to it, i'll explain in more details.
