As can be seen from the human karyogram, the chromosomes are classified into two types, autosomes and sex chromosomes. The autosomes have homologous chromosomes as pairs whereas the sex chromosomes are of two different types - X..

>Culturing of human cells invitro, help in understanding the biochemical basis of inheritance. Human cytology and karyotyping helps in ascertaining the number, shape size and structural features of chromosomes. Study of monogygotic twins helps in distinguishing between..

Giant Chromosomes - There are chromosomes which are extremely large compared to normal chromosomes. Such chromosomes, called giant chromosomes occur in some animal cells. Two types of giant chromosomes are kn..

Structure of Chromosomes - The chromatin material just before cell division forms into chromosomes. Each chromosome is made up of two longitudinal strands called the chromatids. Structure of Chromosome Each chromatid has a double helical DNA molecule. The two..

Chromosomes and Centromere - Centromere is the primary constriction in the chromatid of a chromosome where the spindle tubules become attached during cell division. A chromosome generally has only one centromere and such a chromosome is described as monocentr..

Chromosomes - Chromosomes (chroma = colour, soma = body) are tiny thread-like structures found in the nucleus of a cell. In a non-dividing cell they appear as a chromatin network while during cell division they become condensed to form short and thick chromosomes. ..
