Why do all the daughters in generation 2 carry the colorblind gene?

In genetics, if a colorblind gene is located on the X chromosome, all daughters in generation 2 would inherit this gene from their father, who carries the colorblind trait. Since daughters receive one X chromosome from each parent, they will inherit their father's X chromosome carrying the colorblind gene, while receiving a second X chromosome from their mother. This results in all daughters being carriers of the colorblind gene. If the mother is not a carrier, the daughters will not express colorblindness but will carry the gene.
