In brief: A few things

Often genetic abnormalities arise spontaneously.
Some are due to genetic problems that are passed down in family lines. Some are due to the way the chromosomes from sperm and egg meet and form in an embryo. Lastly, some can be due to exposure radiation which can damage genes. If you're worried that your fetus might have abnormality, you can discuss with geneticist to understand risks.

In brief: Um... Genetics....

The combination of genetic material between parents is a real roll of the dice.
When abnormal genetic material is combined, sometimes you get a combination that is incompatible with life and a fetus never even develops. Other times the combination results in a fetus that can live, but will have developmental abnormalities. Talk to a genetic counselor for specific details.
