Which statement describes the chromosome theory of inheritance?

Alleles for specific traits are carried on a particular chromosome.

Parents pass their genes on to offspring on chromosomes.

The traits of offspring are unrelated to the traits of the parents.

Offspring inherit two copies of each gene from each parent.

Statement that best describes the chromosome theory of inheritance is alleles for specific traits are carried on a particular chromosome.

Explanation:

Based on the observations made by Gregor Mendel, the chromosome theory of inheritance was proposed in 1902 by the scientists Theodor Boveri and Walter Sutton, and confirmed in 1915 by Thomas Hunt Morgan, in his experiments with flies.

Each complete DNA molecule forms a chromosome, and the genes on that chromosome are made up of fragments of that DNA. The chromosomal theory of heredity postulates that the alleles that determine a trait are in the genes within specific chromosomes.

This theory also explains how dominant and recessive alleles are transmitted from parent to child, and that each trait is transmitted independently.
