What are 'sex-linked traits'?

Genes carried by autosomes
Genes carried by sex chromosome
More than two alleles for one gene
Traits controlled by more than one gene

The correct answer is: Genes carried by sex chromosome

Explanation Sex-linked traits are traits that are influenced by genes located on the X and Y sex chromosomes, hence the name "sex-linked." The other options are incorrect because: - A: Genes carried by autosomes refer to any non-sex chromosomes, therefore it is not specific to the X and Y chromosomes. - C: More than two alleles for one gene, while it may be true for some traits, is not the defining characteristic of sex-linked traits. - D: Traits controlled by more than one gene can also be found on autosomes, not just sex chromosomes.
