In this article we will discuss about the chromosome theory of heredity with the help of suitable diagram. By the year 1900, due to improvements in cytological techniques and in the optical properties of microscopes, the behaviour of chromosomes in the cells was studied. William Sutton noticed striking similarities in the behaviour of chromosomes during […]

The word ‘chromosome’ was coined by Waldeyer and means coloured body. Chromosomes are found in viruses, prokaryotes and eukaryotes. 1. Prokaryotic Chromosome: Prokaryotic cells do not possess nuclear membrane and the genetic material is found in a compact structure called nucleoid. A prokaryotic cell possesses a single chromosome which is irregularly folded into a compact […]

According to the chromosome theory of sex determination proposed by McClung, chromosomes play a major role in determination of sex in most of the dioeciously organisms. In diploid organisms, a pair of chromosomes determines the sex of individual. They are called the sex chromosomes or allosomes or heterosomes. Sex determination is the process by which […]
