If my husband, his bro & mom are colourblind but every1 contained by my ancestral is regular, what's the break for my son?

As said, my husband, his brother and mother are colourblind, but his father is not. And everyone in my domestic is normal.
What's the possbility of my son mortal colourblind? Slim to none!
The gene for colour blindness is carried on the X chromosome. Women have 2 X chromosomes - one from respectively parent, but boys have XY - X from mum, Y from dad.
Your husbands mum have 2 faulty X chromosomes, which she passed on to her sons, so they are adjectives colourblind. Your son, however, gets his X from you and his Y from his dad, so he will not be colourlind.
Any daughters you may own will get your ordinary X and their dad's faulty X, so though they will hold normal colour daydream, they will be 'carriers' and their sons will have a 50/50 prospect of being colourblind.
Hope this puts your mind at rest!
If you do not pass the gene for color-blindness, none of your children will be colorblind.
added:
females actually can be color-blind, but single when both parents carry the gene. It is much rarer contained by women than in men, though.
I would enunciate 40-yes 60-no.
because you, and everyone on your side are normal and three relations, including himself are colorblind.
His Mom can't be colourblind. Females never are.
