Definition of Chromosome Theory Of Inheritance



There are some observations that support the chromosomal theory of inheritance. The postulates of this theory are: the chromosomes in an organism are present in the form of homologous pairs. One of which comes from the maternal side and the other from the father. The same pattern is seen in the genes too. These homologous chromosomes are separated during the process of meiosis and these are then sorted into the form of gametes independently.

 


This theory was quite controversial in the start as there was no evidence that showed that the traits were carried through chromosomes. But it was later confirmed by the experiments executed by Thomas Morgan.
