The owl is a generalists creature/species because it is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet). A specialist species can only thrive in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however. Some species are highly specialized (the most extreme case being monophagy), others less so, while some can tolerate many different environments. In other words, there is a continuum from highly specialized to broadly generalist species.
3:1 the dominant allele would show up in 3 and there would be recessive in 1
The Linnaeus's system is based on the similarities in physical traits. It has allowed biologists to group related species into genealogical tees, this represent evolutionary lineage of modern organisms from common ancestors.
IT consist of hierarchy of taxa , the kingdom to species. Each species given a specific/ unique two word Latin name. Added domain is a larger and more inclusive taxon than the kingdom.
This system of Linnaeus's is classified into seven levels. They are , form largest to smallest, kingdom,phylum, class, order, family, genus, species. The first frame principle for defining natural genera and species of organisms and created uniform system for naming that is known as binomial nomenclature.

Adaptive Radiation
After a mass extinction, many habitats are no longer inhabited by organisms because they have gone extinct. With new habitats available, some species will adapt to the new environments. Evolutionary processes act rapidly during these times and many new species evolve to fill those available habitats.
