A variation of language found in a geographically isolated area is called regional dialect.
Dialect is a word meaning a variety of language that signals where a person comes from. Dialect is usually interpreted geographically (regionally) hence the term regional dialect.
A dialect is distinguished from other dialects of the same language mainly by features of linguistic structure such as grammar (specifically morphology and syntax) and vocabulary.
For example wheat known by that name in England while in Scotland it is known as oats. Corn is known by that name in England while in America it is known as maize.
This type of natural selection is referred to as directional selection. In this type of natural selection, either one phenotype is preferred or the other; therefore, there is no equilibrium between the populations of the phenotypes that are present.
Examples of organisms that have undergone directional selection are black bears during the ice ages, African chichlid and sockey salmon.
Constants are factors that are not changed in the experiment. Since the experiment is testing different colors of light on plant growth, light color is being changed, and is therefore not a constant. Hope this helps! :)
Answer: They are sterile
Explanation:
Mule is a hybrid of male donkey and female horse with different chromosome number and is considered superior to both horse and donkey. Still it is considered as a weak hybrid this is because the mule is sterile which means that it cannot reproduce further.

They are sterile and so is a weak hybrid.
