Answer 2

Answer:

D. a trait determined by a gene located on an individual's X or Y chromosome

Explanation:

Sex linked traits are the ones inherited from individual's sex chromosomes. Sex chromosomes i.e. X and Y chromosome not only have genes determining biological sex, but they also have genes coding for other important characteristics. The traits determined by sex chromosomes are known as sex linked traits, they can be either X linked or Y linked. A male has XY chromosome set and a female has XX set. So Y linked traits or the traits whose genes are present on Y chromosome are only passed from father to son. A X linked trait can be passed from both the parents to both the genders.
