    The answer is no Human male can not be carrier for the red green color blindness.

    Explanation:

    Red green color blindness is a sex linked disorder that is recessive in nature. If an individual male have one copy of X gene with recessive allele of the trait he will be color blind because male have only one copy of X chromosomes and one copy of Y chromosome. So, the recessive X chromosome will express itself in absence of dominant X chromosome.

    For being a carrier one should be heterozygous For this gene and its not possible in males as they have only one copy of X chromosome.

    Thus, the correct answer is No.
