To determine whether a trait is sex-linked, you would examine the following:

1. Pedigree: A pedigree is a diagram that depicts the biological relationships between an organism and its ancestors. It is often used to analyze the pattern of inheritance of a specific trait. If a trait is sex-linked, it will often appear more frequently in one sex than the other.

2. Karyotype: A karyotype is a picture of all the chromosomes in a cell. If a trait is sex-linked, it will be located on one of the sex chromosomes (X or Y). Examining a karyotype can help identify if a trait is linked to these chromosomes.

3. DNA Sequence: By examining the DNA sequence, you can identify the specific genes associated with a trait. If a trait is sex-linked, the gene for that trait will be located on the X or Y chromosome.

4. Blood Test: A blood test can be used to identify the presence of certain proteins or enzymes that are produced by genes located on the sex chromosomes. This can help determine if a trait is sex-linked.

Remember, a trait is considered sex-linked if it is caused by a gene located on a sex chromosome.
