Q: What is a trait whose allele is found on a sex chromosome called?


Read this paragraph and choose the correct option from the provided answers:

A sex-linked trait is a trait whose allele is found on a sex chromosome. The human X chromosome is significantly larger than the Y chromosome; there are many more genes located on the X chromosome than there are on the Y chromosome. As a result there are many more X-linked traits than there are Y-linked traits. Most sex-linked traits are recessive. Because males carry only one X chromosome, if they inherit a recessive sex-linked gene they will show a sex-linked condition; there is no dominant allele to offset the recessive allele.

 Choices:

- dimorphism - linked trait

- gender trait

- genomic trait

- sex-linked trait


A:
sex-linked trait
