Here's a breakdown:
* Homologous chromosomes are pairs of chromosomes that carry the same genes in the same order. They are not identical, as they may have different alleles (versions) of those genes.
* Alleles are alternative forms of a gene.
* Humans have 23 pairs of homologous chromosomes, making a total of 46 chromosomes. One chromosome from each pair is inherited from the mother, and the other is inherited from the father.
Example: Let's say a gene for eye color is found on chromosome number 15. You'd inherit one copy of that gene from your mom on her chromosome 15, and another copy from your dad on his chromosome 15. These two chromosomes would be considered homologous, even though the genes for eye color might be slightly different (one might be brown eyes, the other blue).
