How can my child have a condition passed from us if we are healthy?
... Cells contain ‘genes’. Genes are the ‘instructions’ telling our bodies how they should be made. There are two copies of each gene in our cells. We inherit one copy from our mother and one from our father. This is how genes are passed on in families and that is why we all look a bit like our family. ...
