So, homologous chromosomes satisfy two things. First of all, they have similar size, they have similar structure and similar shape. And second of all, they have genes that code for similar proteins that express the same exact trait. So number two is the important criterion for homologous chromosomes. So they carry genetic information, so they carry the genes that have the same type of information, that code for those same types of proteins that help us express some given trait. So if we, for example, take one chromosome and that chromosome contains, let's say, the seed color, then it's homologous chromosome will also contain a corresponding gene that creates proteins that expresses the seed color.
