I've never known what homologous chromosomes are. My friends all say these tests need to be done afterward, but I'd like to know: what exactly is the concept of homologous chromosomes?

Homologous chromosomes refer to a pair of chromosomes that are generally identical in morphology and size, with one inherited from the father and the other from the mother. Homologous chromosomes appear as two chromosomes of equal length and with identical centromere positions during metaphase of mitosis, and they can also be observed as paired chromosomes during meiosis. The appearance of homologous chromosomes varies at different stages; they are a concept in biological genetics.
