Question

Which statement about sex-linked traits in humans is correct?

1.) Hemophilia and color blindness are examples of recessive sex-linked traits.

2.)The gene involved in most sex-linked traits is located on the Y-chromosome.

3.)The sex-linked traits are found more frequently in females than in males.

4.)There are no sex-linked traits in humans.

Answer 1

Answer:

The correct answer is option 1.

Explanation:

Hemophilia and color blindness are recessive sex-linked traits in humans that present on the X-chromosome. Hemophilia is a blood clotting disorder that prevents blood clotting.

Color blindness is the disorder that develops a condition where an individual can not distinguish between red and green color.

It is more frequent in males than females because males have only one copy of the X- chromosome.

Thus, the correct answer is option 1.
