But this will not be expressed because by the law of dominance we have a dominant trait will basically inhibit the expression of that recessive trait. So also notice that because homologous chromosomes have similar size, shape and structure, each allel pair are found at similar locations along the chromosome that is at a similar locus. So if g number one for height is found on the top at this locus, then on the homologous chromosome, the locus will also be found in that location on the top of that chromosome. That's exactly what we have here. We have essentially a perfect pairing of these alleles. Now, as I mentioned earlier, and this is an important point, even though each allele pair contains similar genes, the genes that code for similar traits, the genes do not have to code for identical traits.
