Is it possible to be Tt for the trait for height and be short?

Yes having 6 fingers on your hand is a dominant trait. Most people who have this trait get the extra finger cut off after birth. There is a small group in the world where the people there have 6 fingers.
The two different extreme variations in a trait are favored in what?
Two extreme variations in a trait are favored in the evolutionary phenomenon of disruptive selection. This leads to rapid genetic evolution of a population.
The two different extreme variation in a trait are favored in?
disruptive selection.
What is selection where one of the extreme forms of a trait is favored?
It is directional selection.
The form of natural selection in which one extreme in the range of a phenotypic trait is favored is termed?
Plato answer is A: Directional
The different ways that a trait appears are called?

What is disputive selection?
When natural selection favors extreme variations of a trait (ex. Biggest & Smallest)
What types of individuals in a population are represented by the two ends of a bell curve?
The individuals with extreme variations of a trait.
What types od individuals in a population are represented by the two ends of a bell curve?
The individuals with extreme variations of a trait.
What is the definition of disruptive selection?
Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored
Are all different types of traits the result of adaptation.explain?
No. You are describing what is called Lamarckism. Different traits are the results of the alleles found in genes. The environment does push one trait over another if the environment becomes extreme. You will see many traits in a population (such as in a human population) but one is not favored unless that trait allows those that have it to do better.
Why are there 2 different variations of a trait?
Because there has to be more than one or we would be all the same
When many genes contol a trait the trait will show a large number of what?
