So basically, such a pair of genes, such a pair of genes found on homologous chromosomes that code for polypeptides, that express the same physical trait. In this case, it's the height. In this case, it's the seed color, the pod color, the seed shape and so forth. These are known as alleles. So alleles are basically two genes that are located on homologous chromosomes that code for a similar polypeptide, a similar protein that gives us or helps us express that same type of trait. So in this particular homologous pair, we have 1234 genes on this chromosome, 1234 genes on this chromosome.
