Chromosome behaviour is an important factor that determine the pattern of variation and taxonomic distinctness. Pairing behavior and subsequent separation of chromosome occurs at meiosis. In reporting results of pairing studies, univalents are represented by Is, bivalents by IIs, etc. Some taxonomic information can be gained from the study of …

Study of chromosome structure is very important in cytotaxonomic studies. It includes chromosome size, shape and position of centromere (i.e. arm-length ratio of each chromosome in the genome) Chromosomal size and shape are also important as taxonomic criteria in taxonomy. For examples, The chromosomal ratio if Mediola and Trillium of …

DNA replication in eukaryotes is a complex and unique process involving many enzymes and thousands of ORI at a single time. Unlike the prokaryotic DNA, it involves a linear mode of replication. Why does linear DNA replication involve  multiple origins at a time? The large linear chromosomes in eukaryotic cell …
