Explanation / Answer

Option 2 and option 5 are the correct answers.

Y-linked traits are present on Y sex chromosomes which can not be inherited by Female offsprings as females have XX-chromosomes only as sex chromosomes hence, Y linked traits can not be expressed by any female offsprings. Also, the only Y chromosome in males is inherited by fathers only, hence a Y-linked trait will affect all male offsprings of the affected father.
