DNA is stored on chromosomes, and chromosomes are passed through generations.
Mendel's conclusions, based on his pea plant experiments, included the principles of segregation and independent assortment. These principles describe how genes are passed down from parent to offspring. The chromosomal theory of inheritance later connected Mendel's principles to the physical basis of heredity by identifying chromosomes as the carriers of genetic information, thus explaining how genes are inherited and expressed through the process of meiosis and fertilization.
Deletion: loss of a chromosomal segment. Duplication: repetition of a chromosomal segment. Inversion: reversal of a chromosomal segment. Translocation: movement of a chromosomal segment to a new location on a different chromosome.
An episome carrying a chromosomal fragment is known as a F-prime (F') plasmid. It contains part of the bacterial chromosome along with the F plasmid DNA. The chromosomal fragment can be transferred between bacteria during conjugation.

Chromosomal mutations involve changes in the structure or number of chromosomes in an organism's cells. This can result in genetic disorders, such as Down syndrome, or impact an individual's physical and cognitive development. Chromosomal mutations can occur spontaneously or be influenced by environmental factors.
Boveri & Sutton.
The founder of the chromosomal theory of inheritance is Walter Sutton, an American geneticist, who proposed that genes are located on chromosomes and that chromosomes are the basis of Mendelian inheritance.

The chromosomal theory of inheritance was proposed and developed by one Walter Sutton and Theodor Boveri.
Presence of extra-chromosomal DNA: Mitochondria and chloroplasts
False they aren't carried by gravity
Exceptions to the Chromosomal Theory of Inheritance include genes located on organelle genomes (like mitochondria and chloroplasts), which are inherited independently of nuclear chromosomes. Additionally, certain genetic elements like transposons can move between chromosomes and affect inheritance patterns. Lastly, epigenetic modifications can also influence gene expression and inheritance independently of chromosomal DNA sequences.
Chromosomal Loci is a Heterozygous
There is no actual chromosomal change, there is an extra chromosome.
Chromosomal mutation can have lasting impacts on the person who this happens to. A version of a chromosomal mutation is the mutation that leads to Down's Syndrome.

Diploid cells are cells with full chromosomal number.Haploids are with half chromosomal number.
