The daughters will inherit one X chromosome from each parent. Since the father has normal vision, he will pass on a normal X chromosome. The mother, being color-blind, will pass on an X chromosome with the color-blind allele. Therefore, none of the daughters will be color-blind as they will all have one normal vision allele from their father. However, they will all be dwarfs because achondroplasia is autosomal dominant, and the father is a dwarf.
