Yes. A person is color blind if all his or her X chromosomes have the defective gene. A man have one X chromosome, and a woman has two. Thus:

If only the father is color blind

- The probability that the son is color blind is 0%

- The probability that the daughter is color blind is 0%

- The probability that the daughter is a bearer of the defective gene is 100%

If the mother is a bearer of the defective gene, but is not color blind, and the father is not color blind

- The probability that the son is color blind is 50%

- The probability that the daughter is color blind is 0%

- The probability that the daughter is a bearer of the defective gene is 50%

If the mother is a bearer of the defective gene but not color blind, and the father is color blind

- The probability that the son is color blind is 50%

- The probability that the daughter is color blind is 50%

- The probability that the daughter is a bearer of the defective gene is 100%

If the mother is color blind and the father is not

- The probability that the son is color blind is 100%

- The probability that the daughter is color blind is 0%

- The probability that the daughter is a bearer of the defective gene is 100%

If both parents are color blind

- The probability that the child, regardless of gender, is color blind is 100%
