Answer   Chromosomes are located in the nucleus of a cell in eukaryotes. In prokaryotes (which lack a cell nucleus) chromosomes are circular in shape usually found â¦ attached to the plasmid membrane.
Genes are located on chromosomes. Chromosomes are in pairs and genes, or their alleles, are located on each of these pairs. When the cell divides in half, each chromosome ends up in a different cell. This is seen during meiosis in formation of egg cells of sperms. The genes also split into two halves. These are called alleles.
