Perhaps you should have listened a bit more when your biology teacher was talking about evolution, even if you believe in creationism, you would have picked up the basics of genetics.

Mutations do get passed on to offspring.
The chance of it depends on whether the mutated genes are dominant or recessive, and if both parents have it.

Lets say you have two adults, both have a recessive gene for webbed hands.
Let N be the normal gene, W be the web gene.

Both parents are NW (normal dominant, web recesive)
Now the bloke will produce sperm with N or W genes, and the woman will produce ova with either N or W genes.
So the possible outcome is children with :

NN (perfectly normal, no chance of passing web hands on)
WW (totally webbed hands, can only pass the W gene on so has to be careful if reproducing with a WN or NW partner)
NW (normal but may have some web)
WN doesn't happen because W is a recessive gene

So they have 25% of kids with webed hands, 50% with normalish and carrying the W gene, and 25% with webbed hands
