Will birth defects transferrable to kids?

most genetic change is caused by more then one gene, and those genes can all be recessive or dominant. Even if your lucky enough to narrow a problem down to one gene, the chance of passing it on to being expressed in the next generation can range from 75% to 0% depending on whether your mate carries the same gene and whether the gene is dominant or recessive.

Then there is the possibilty that the defect isn't genetic, it could be epigenetic, it could be the result of chemicals, drugs, or other ways that development can normally be disturbed.

In other words, only after a thorough examination of the individual involved and who they plan on having children with by a doctor in the appopriate field can a statistic reliable be found for passing such a defect on to the next generation.

But yes, half your DNA is passed on to the next generation randomly to mix with half of your mates DNA, although the Y chromosome is obviously only come from the male, and important organelles such as mitochondria (used for cellular respiration) only come from the female.

Birth defects can only be passed on if they are genetic or epigenetic based, not if they are chemical or enviromentally induced during development.

Both answers are really true. Some birth defects such as spina bifida and fetal alcohol syndrome are preventable by taking proper care before and during the pregnancy by taking folic acid supplements and abstaining from alcohol use respecively. A younger woman has less of a chance to deliver a baby with down's syndrome than an older woman. Some birth defects are not necessarily preventable. Some are genetic.

It depends on the cause of the premature birth and defect and whether it is genetically caused. If it was not due to genetics then it is unlikely to transfer the defect. Kids do have a mix of the parents DNA, and anything genetically linked can be passed down.

If it is a genetic defect hten its a possibility the baby will have this defect, if it not genetic then the child may not have the defect. Such as down syusndrome, this is a genetic defect, and aperson being born with more fingers or toes, is a birth defect, and the child may or may not have it.

The baby's DNA is a mixture of both parents. Some traits are dominant (meaning that there is 75% chance that the child will have the trait) and some traits are recessive (meaning that there is only a 25% chance or less that the child will have the trait). There are doctors that perform genetic testing on the parents to find out what the likelihood is that the child will have certain traits.

I asked a question like this a while back. My husband is deaf, and I am not. I was wondering if our children would have it, and it's the same chance as someone without being deaf to have a deaf child. It really depends on the gene and how rare it is. If you are planning on doing stuff like that though, talk to a doctor.
