Generally the trait is on the X chromosome, as the Y is rather small and full of deleterious mutations and has few working genes. But and trait that is located on a sex chromosome is said to be sex linked. Naturally, women have two, XX, chromosomes, so ore protected statistically from many sex linked recessive disorders.

When discussing genetics, recessive trait refers to the fact that the offspring of two parents must inherit two copies of a gene to expose the trait. This would mean that both parents must be carriers of said gene in order for their offspring to show a recessive trait.

dominant trait means homozygous

It should be a dominant allele--a dominant allele's trait will be expressed over the recessive allele's trait.

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.
