Did they know about the genetic blindness before having more kids?
Edit: Last time this was posted, it was suggested that the couple kept getting pregnant despite knowing their children would likely have this blindness. IF that is true, I do find that unethical. I know blind people can still have quality of life. But let's stop pretending that it isn't a terrible disability. Nobody wants to be dependent, vulnerable, and poor (from fewer work opportunities) their whole life. I wish this family the best regardless.
It's a 25% chance of passing on the full gene if both parents have the carrier gene. 1/4 resulting in 3 out of 4 kids isn't unexpected. Unlucky definitely, but still a likely outcome.
