What role do genes and chromosomes play in the hereditary process?

1 answer:

6 0

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. These pair up to make a total of 46 chromosomes.
