Summary Introduction
Introduction:
A couple of one maternal and one paternal chromosome that undergo pairing upon meiosis are called homologous chromosomes. They are with the same length and size but with different DNA sequence as they are inherited from two different parents but they have the same genes in the same order in their chromosomal arms.
