So, let's take one of these 23 pairs as shown in the following diagram. So this is our pair of homologous chromosome. So we have homologous chromosome one and homologous chromosome two. Now, these two chromosomes are genetically different from one another. One of these chromosomes, let's say the purple one, came from the male, and the other one, let's say the brown one, came from the female parent. So these are genetically different, but they are homologous.
