"Two chromosomes of a pair carry the same genes in the same order, but the specific versions (alleles) of those genes may differ."
Here's why:
* Homologous Chromosomes: We inherit one chromosome from our mother and one from our father. These are called homologous chromosomes, meaning they have the same genes in the same order.
* Alleles: While the genes are the same, the specific versions of those genes (called alleles) can differ. For example, one chromosome might carry the allele for blue eyes, while the other carries the allele for brown eyes.
* Genetic Variation: This difference in alleles is what contributes to the genetic diversity within a population.
