"Homologous" is used instead of "identical" because it describes structures or sequences that share a common origin or evolutionary ancestry, even if they are not identical in form or function. For example, homologous chromosomes carry the same genes but may have different alleles. In contrast, "identical" implies an exact match in structure or sequence. Thus, "homologous" acknowledges the nuanced relationships between similar entities that arise from evolutionary processes.
homologous
Structure and identical are not similar. Structure refers to the way something is organized or built, while identical means exactly the same.
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
Homologous chromosomes do not have identical DNA sequences; while they carry the same genes, the alleles (variations of those genes) can differ between the chromosomes. Additionally, homologous chromosomes can vary in size, shape, and genetic content due to the presence of different alleles and possible structural differences. Thus, the key characteristic that is not true for homologous chromosomes is that they are not identical in sequence.

they sure do
The only homologous chromosome pair in humans that is not identical is the sex chromosomes, specifically the X and Y chromosomes.
Homologous pairs
Homologous chromosomes are not identical to each other, but they have the same genes in the same order. They come from each parent and carry similar genetic information.

Homologous chromosomes
Chromosomes that appear identical are called homologous chromosomes. They carry the same genes in the same order but may have different versions of those genes (alleles). Homologous chromosomes are inherited, one from each parent, and are important for genetic variation and the process of meiosis.
