Question

Think about how genes determine traits. Describe one example of a trait that could be affected by a sex-linked gene and explain why. (Write 2–3 sentences.) in 6th garde words

Answer 1

Red-green color blindness is a trait that can be caused by a sex-linked gene; people with it have trouble telling red and green apart. It happens because the gene is on the X chromosome, and boys (who have one X) are more likely to show the trait than girls (who have two Xs).
