• Centromere location

• Size

Which of the following best defines an autosome?

• A chromosome that does things automatically

• A chromosome that is least common in a human set of chromosomes

• A non-sex chromosome

• A sex-determining chromosome

The reason why sex chromosomes have they name they do is because they
