Inheritance Intermediate, Dominance and Polygenic

When talking about genetic inheritance and especially when the work of the Monk Gregorio Mendel is known, we must be clear that there are three types of inheritance:

1. Codominant inheritance
2. Intermediate inheritance and
3. Polygenic inheritance

Example of intermediate inheritance or dominance and polygenic inheritance:

Heredity is understood as the information contained in the genes of living beings.

These laws were produced when a series of experiments was empirically analyzed by this monk that resulted in the inheritance of characteristics of the one who was called dominant gene, which could be explained as a characteristic that is transmitted and dominates over the others by partially displacing the characteristics of the gamete opposite.

These are the ones that form the first law "dominant gene”, It is precisely this gene that presents its characteristics, letting those of the opposite gamete appear.

1.- “Codominance".- A red flower dominates over a white one and the flowers come out red but exceptionally after a few generations a white one comes out from among the red flowers.

In this sense, depending on the racial circumstance of the parents, the percentage or the dominant gene in the children will be inclined.

2.- Intermediate inheritance.- This occurs when two relatively opposite entities come together and their product gives an intermediate entity between them, exemplifying with flowers, it can be said:

That white flowers and black flowers result in pink flowers in all their offspring. Here it would be considered that a proportion of 50% is presented.

3.- Polygenic.- This aspect is the one that establishes the constant variables of the descendants, that is, they can vary indeterminately in the members of a family; in people, polygenetic genes control relevant aspects such as:

• Height
• Weight
• Eye color
• Intelligence
• Skin color
