Question

Which genes are present on sex chromosomes?

• A. Sex linked genes
• B. Autosomal genes
• C. Chromosomes genes
• D. None of the above

Answer 1

Answer: (A)

Sex linked genes

Genes are the stretch of DNA present on chromosomes in a linear fashion. All the genes are present on chromosomes only. Sex-linked genes are present on the sex chromosomes. They determine the sex-linked traits and are transmitted from parent to progeny through sex chromosomes only. Any chromosome other than sex chromosome is referred to as autosome which controls normal traits of an organism, not the sex-specific traits. The genes present on autosomes are referred to as autosomal genes. Thus, the correct answer is option A.
