Which of the following is not a sex linked trait? a) male patterned baldness b) color blindness c) hemophilia d) none of the above

The correct answer is option D, that is, none of the above, as all the mentioned conditions come under sex-linked trait.  

The sex-linked traits are the usual features determined by the genes situated on the sex chromosomes. Sex chromosomes are witnessed within the reproductive cells and predict an individual's sex. Male pattern baldness refers to the continuous thinning of the hair on the head finally leading to baldness. The condition is considered as the sex-linked trait.  

Color blindness is usually an inherited genetic disorder. It is most usually inherited due to mutations on the X chromosome. Hemophilia is inherited in an X-linked recessive pattern. The genes related to the condition are situated on the X-chromosome.
