The best description for chromosomes that contain genes for the same characteristics is homologous chromosomes.

Here's why:

* Homologous chromosomes are pairs of chromosomes that have the same genes in the same order. They come from each parent, making them a matched set.

* Genes are segments of DNA that code for specific traits.

* Since homologous chromosomes carry the same genes, they are responsible for determining the same characteristics.
