Question

Quizplus · Accepted Answer

The two copies of each chromosome in body cells are homologous chromosomes, which means they contain the same genes in the same order but may have different alleles (versions of the gene). Chromatids refer to the two identical copies that are produced when a chromosome replicates during cell division. Sister chromosomes and daughter chromosomes both refer to chromosomes that result from the separation of chromatids during cell division, but they do not necessarily refer to the two copies of each chromosome in body cells. Genes are segments of DNA that encode for specific traits and may be found on either homologous chromosome.
