WebChromosomal Theory of Inheritance The chromosomal theory of inheritance is the idea that genes, the units of heredity, are physical in nature and are found in the … WebThe Chromosomal Theory of Inheritance was consistent with Mendel’s laws and was supported by the following observations: During meiosis, homologous chromosome pairs migrate as discrete structures that are independent of other chromosome pairs. The sorting of chromosomes from each homologous pair into pre-gametes appears to be random.

WebHis theory states that multicellular organisms consist of germ cells that contain and transmit heritable information, and somatic cells which carry out ordinary bodily functions. [1] [2] In the germ plasm theory, inheritance in a multicellular organism only takes place by means of the germ cells: the gametes, such as egg cells and sperm cells. WebSummary.
