Detailed explanation-1: -Hemophilia is a sex-linked recessive disorder. The abnormal gene responsible for hemophilia is carried on the X chromosome. Males have one X chromosome and one Y chromosome.
Detailed explanation-2: -It is a sex-linked recessive disorder that is characterized by the inability to differentiate between red and green color. Reason for the occurrence of this disorder more in males than females: Both males (XY) and females have the X chromosome (XX). Males have only one X chromosome (XY).
Detailed explanation-3: -X-linked recessive diseases most often occur in males. Males have only one X chromosome. A single recessive gene on that X chromosome will cause the disease.
Detailed explanation-4: -Males are affected more often than females, because the gene is located on the X chromosome.
