Answer:

Each gene occupies a specific position on a chromosome. Because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body, it follows that genes are responsible for all the characteristics you inherit.

The roles of DNA and genes in inheritance and genetic variation are the following:

  • Inheritance is understood as the sum of the processes by which the characteristics of living beings are transmitted from parents to their descendants.

  • This transmission occurs thanks to genes, minimal units of biological information contained in chromosomes and expressed molecularly in the DNA matrix.

  • Much of the variation in individuals comes from genes, that is, it is genetic variation.

  • These variations in the DNA sequence explain the genetic differences that exist between different individuals of the same species (genetic variation).

Therefore, we can conclude that genes contain the DNA (genetic information) of a living being, which is responsible for inheritance and variations in that DNA sequence lead to genetic variation.
