Verified step by step guidance

Understand the question is asking for the basic unit of heredity on a chromosome.

Recall that a chromosome is made up of DNA and proteins, and contains many segments called genes.

Recognize that a gene is a specific sequence of DNA that codes for a trait and is the fundamental unit of heredity.

Differentiate the other options: a centromere is the chromosome's constricted region, a chromatid is one half of a duplicated chromosome, and an allele is a variant form of a gene.

Conclude that the correct answer is 'gene' because it is the basic unit responsible for transmitting hereditary information.
