Genetics: Codominance

Codominance

Codominance is a type of non-Mendelian genetics that implies that there is no trait that is recessive. Both of the traits are equally dominant and will show. 

An example could be, a black chicken mixed with a white chicken, would result in a checkered chicken. The chicken is neither all black, nor all white. But it shows both the black and the white because both of the traits are dominant.

Codominance could be used outside of biology when you are trying to determine what your flowers in your garden are going to look like next year, or for a farmer, what color fur your animals could have.

A visual example of a brown cow mixing with a white cow, to create a brown and white cow would look like the picture below.

Personally, I liked this objective in the unit. I thought it was interesting to learn about how genetics can basically influence your whole life, and it was cool to learn about the different kinds of genetics.
