Question

Usually male child suffers from color blindness.

Answer 1

Usually male child only suffers from colour blindness as the gene for disease colorblindness are located on X-chromosome (sex-linked recessive disorder). Males have only one X-chromosome so the expression of the gene does not take part in dominant-recessive relationship it just gets expressed. While the females consist of two X-chromosome so a female is generally carrier of the colorblindness and rarely sufferer. For a female to be a sufferer of the disease she needs to have the gene for the disorder on both of her X-chromosomes.
