Question

46. Which of the following is NOT a sex-linked disorder?A. hemophiliaB. color blindnessC. albinism

Answer 1

Answer: Colour blindness

Step-by-step explanation:

A. hemophilia: It is a sex-linked disorder. The abnormal gene responsible for hemophilia is carried on the X chromosome. Males have one X chromosome and one Y chromosome.

Colour Blindness: Its a disorder of not able to distinguish between certain colours.

Ablinism: group of inherited disorders where there is little or no production of the pigment melanin. The type and amount of melanin your body produces determines the color of your skin, hair and eyes.

Answer 2

Step-by-step explanation:

Sex-linked diseases are passed from parent to child through one of the X or Y chromosomes. Both color-blindness and hemophilia are hereditary diseases linked to the X chromosome. In X-linked recessive inheritance, the incidence of the trait is much higher in males than in females. On the other hand, heterozygous women do not usually present involvement, but some express the disease with variable intensity, depending on the mosaicism that they can present. In this type of inheritance, the mutant allele is usually never transmitted directly from a father to his son, but affected men pass it on to their daughters.

We can conclude that the correct answer is:

Answer:

C. albinism
