WebWhat is the difference between an allele and a chromosome? Solution Allele: A form of a gene at a specific location (locus) on a chromosome is known as an allele. Chromosome: Chromosomes are a component of the cell's nucleus. Chromosomes are found in pairs, each gene in an organism has two alleles, one on each chromosome of the pair. WebChromosomes and cell division. As a cell prepares to divide, it must make a copy of each of its chromosomes. The two copies of a chromosome are called sister chromatids. The …
