Which of the following is an example of a sex-linked trait? (2019)
Step 1: Understand what a sex-linked trait is. A sex-linked trait is a characteristic that is associated with a gene located on a sex chromosome (X or Y).
Step 2: Know that males have one X and one Y chromosome (XY), while females have two X chromosomes (XX).
Step 3: Recognize that traits on the X chromosome can affect males more than females because males have only one X chromosome.
Step 4: Identify color blindness as a specific example of a sex-linked trait. It is caused by a gene on the X chromosome.
Step 5: Understand that since males have only one X chromosome, if they inherit the gene for color blindness, they will express the trait. Females, having two X chromosomes, would need to inherit the gene from both parents to express color blindness.
