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. So if we take a look at the following diagram, if this is, let's say, chromosome number one, and this is its homologous chromosome, what that means is this will contain a gene in this locus that will code for height. And this homologous chromosome will also contain a similar gene that will also code for a protein that will help us express our height. And these two genes, with respect to one another, these two homologous genes are known as alleles or alleles.
