Human blood type exhibits codominance as well as normal Mendelian inheritance (known as dominant/recessive)
Explanation:
Neither the A gene nor the B gene is dominant to the other. They both share in the phenotype AB blood type. Think of co-captains of a team sharing responsibilities.
A and B are both dominant to O which is recessive. If a person inherits A & O they have blood type A. Likewise, if a person inherits B & O they have blood type B. Only if they inherit O & O (homozygous recessive) will they have type O blood.
An operational definition is used to define the terms of a process which is needed to determine the nature of an item such or its properties such as quantity, chemical composition, etc.
The degree of operationalization vary.
Operational definitions can be defined as labels and concepts in the way they are measured.
For example: The operational definition of weight can be like this:
How many pennies are needed to balance the weight of something.
When we hang something from a spring, how much a spring streches.
Reduce the number of trips you take in your car. Reduce or eliminate fireplace and wood stove use. Avoid burning leaves, trash, and other materials. Avoid using gas-powered lawn and garden equipment.
