A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during meiosis.
We know that homologous chromosomes have to pair up during meiosis, but exactly how they do this remains a bit of a mystery. One of the tricky things about studying homologous chromosomes is that different species use different mechanisms for pairing their chromosomes.
