DIFFERENCE BETWEEN MONOGENIC INHERITANCE AND POLYGENIC INHERITANCE

  DIFFERENCE BETWEEN MONOGENIC INHERITANCE AND POLYGENIC INHERITANCE

Monogenic inheritance

1)   Monogenic inheritance refer to genetic control of a trait.

2)   monogenic inheritance control qualitative traits.

3)   monogeneses produce discontinuous variation in the expression of traits.

4)   F1 individual are smaller to the dominate parent.

5)   F2 individual are similar to the dominant parent.

6)   No intermediate are produce.

7)   Individual with dominate phenotype are more numerous then with recessive                  

       Phenotype.

8)    There is no commutative action in the presence of dominate phenotype.

Polygenic inheritance

 1)  polygenic inheritance refers to the genetic control of a trait by means gene.

2)    Polygenic inheritance control quantitative traits.

3)    Polygenic produce continuous variation in the expiration of traits.

4)   F1 individual are intermediate between two parent.

5)   F2 individual resemble the parent on basis number.

6)    Intermediate are quite common.

7)    Intermediate are more numerous, individual with dominate traits are as few with recessive trits.

8)      The dominate gene have commutative effect on the expression of the trait.
