Variation in Structure of Chromosome
Subject: Biology | Topics:

Basic objective of this lecture is to present on Variation in Structure of Chromosome.  The somatic (2n) and gametic (n) chromosome numbers of a species ordinarily remain constant. This is due to the extremely precise mitotic and meiotic cell division. Somatic cells of a diploid species contain two copies of each chromosome, which are called homologous chromosome. Their gametes, therefore contain only one copy of each chromosome, that is they contain one chromosome complement or genome.
