Answer 2

Answer:

Within cells, the long strands of DNA form condensed structures called chromosomes. Organisms inherit genetic material from their parents in the form of homologous chromosomes, containing a unique combination of DNA sequences that code for genes.

Explanation:

Chromosomes contain genes which carry hereditary characteristics of a particular person i.e shortness, tallness, brown eye colour etc. Therefore, chromosomes are called hereditary vehicles. Chromosomes are called hereditary vehicles because they are inherited to the offspring from their parents and to their offspring from them.
