Chromosomal theory of inheritance suggests that:
Correct answer: D. All of the above
- A. Genes are present on DNA
- B. Genes are present on chromatids
- C. Genes are present on chromosomes
- D. All of the above
Explanation
The chromosomal theory of inheritance suggests that genes, the units of heredity, are located on chromosomes. This theory proposes that chromosomes, which contain DNA and associated proteins, carry the genetic information that determines an organism's traits. It also explains how traits are passed from parents to offspring during the process of cell division, such as during meiosis and mitosis.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
