Answer 1

Following are the matches:

Color blindness: Disorder that affects the ability to, in most cases, distinguish red from greens.

(Color blindness is X-linked recessive trait. It is generally transferred from mother to sons)

Fragile X syndrome: Disorder that is most common cause of inherited mental impairment including the most common cause of autism.

(It is a genetic disorder where individual suffering from the syndrome displays a range of intellectual disability. Males are more prone to this syndrome as compared to females).

Hemophilia: Disorder caused by the absence or minimal presence of factor VIII or factor IX, reducing blood clotting.

(Hemophilia is also an X-linked recessive trait and similar to color blindness, the disease is transferred from mother to son).

Duchenne muscular dystrophy: Disorder caused by the lack of dystrophin and characterized by wasting away of the muscles.

(It is a genetic disorder where individuals suffering from this disease show muscle degradation resulting in general weakness. It is caused due to protein alteration (dystrophin alteration).
