A Conversation for Colour Blindness
Lyonisation.

I would just like to know if anyone can tell me if due to lyonisation, a female carrier can have a completely unaffected male son.
Her father is colour blind and one of her sons is colour blind but her other son is not. Obviously I'm unsure as to the genotype of her mother.
