What chromosome controls a characteristic?

Autosomes control the inheritance of all the characteristics except the sex-linked ones, which are controlled by the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes. All act in the same way during cell division.

What is the name of a chromosome that controls a characteristic?

DNA determines the characteristics of a living organism. … A gene is a small section of DNA on a chromosome that codes for a particular sequence of amino acids, to make a specific protein. It is the unit of heredity, and may be copied and passed on to the next generation.
