what is the difference between homologous chromosomes and sister chromatids
It is produced from the duplication of the chromosome in the early stages of cell division. There are two forms of chromatids, sister or non-sister chromatids. Sister chromatids are two identical copies of a chromatid having the same genes and alleles. Non-sister chromatids are also called homologues having the same length, staining pattern, centromere position, as well as the same characteristics of genes at a particular loci.
