hi seemslost
well i think i would be hurt for having not been told but then thinking about it i would realize that in the gooeyness of love, none of that stuff matters. couples believe they can conquer anything that comes along.
that being said, if i remember my highschool biology, i think it is only a 25% chance of passing it along if one party is carrying the gene. it has to be a recessive gene or that party would have the illness which means they would be contributing a good gene and a tainted gene to the gene pool along with the other persons 2 good genes.
and what is so horrible if the child does get it? blind people are people too. it is a disability like any other that you would have to deal with and one that has had many advances in society to deal with it. my child started going blind at 8 due to a genetic issue we knew nothing about. he got special services in school, all kinds of advantages. fortunately within 6 years he had transplants and could see again, so i know it isnt quite the same. but people with disabilities are strong, they overcome challenges. you raise them to do that.
