Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
Most sex-linked genes are found on the X chromosome
Sex-linked genes are genes that are located on the sex chromosomes. Since the X chromosome is so much larger than the Y chromosome, most sex-linked genes are X-linked.

A gene or allele may take a dominant form, or a recessive form. If the allele is recessive, the characteristic which is coded for will be exhibited only if both the gene from the male and the gene from the female is recessive. Only one copy of a dominant allele is required to cause expression of the dominant characteristic
A copy of your mother's gene for a characteristic would go to a different daughter cell than the copy of your father's gene for the same chromosome.Read more: Which_of_these_would_occur_as_a_result_of_independent_assortment_of_homologous_chromosomes
Yes. Because the colorblind trait is a sexlinked trait and is found in the X chromosome that is inherited from the mother, men that only have one X chromosome will develop colorblindness if the trait is found in this gene. For a woman to get it, she would need to have the colorblind gene on both x chromosomes. Therefore the girl´s dad would have to be colorblind and the mother at least a carrier.
