Is down syndrome a sex linked trait
WebSex-linked traits are characteristics that are determined by genes located on the sex chromosomes. Inheritance patterns for these traits can differ for males and females, since the X and Y chromosomes differ. One example of a sex-linked trait is color blindness, which is primarily seen in males. WebMales are more often affected by sex-linked traits than females because A) male hormones such as testosterone often alter the effects of mutations on the X chromosome. B) …
