Provide a brief description of discontinuous inheritance and continuous inheritance. How are the two related? How are they different?
What will be an ideal response?
At the transmission level, one sees "stepwise" distributions in discontinuous inheritance, but "smoother" or more bell-shaped distributions in continuous inheritance, as shown in the following figures:
Both patterns are formed from normal Mendelian principles of segregation and independent assortment. The differences are in the manner in which the gene products interact; continuous inheritance involves additive effects.
