Can a human male be a carrier of red-green color blindness?
Yes, males can be carriers of red-green color blindness, as color blindness is autosomal dominant
No, males cannot be the carriers of red-green color blindness, as color blindness is X-linked
No, males cannot be the carriers of red-green color blindness, as color blindness is Y-linked
Yes, males can be carriers of red-green color blindness, as color blindness is autosomal recessive
