Correct!

OpenStudy (igreen):

"A couple of homologous chromosomes is a set of one maternal chromosome and one paternal chromosome that pair up with each other inside a cell during mitosis. These copies have the same genes in the same locations, or loci. These loci provide points along each chromosome which enable a pair of chromosomes to align correctly with each other before separating during meiosis.[1] This is the basis for Gregor Mendel’s laws of genetics that characterize inheritance patterns of genetic material from an organism to its offspring."

OpenStudy (igreen):

*** These copies have the same genes in the same locations ***
