Taxonomy, or taxonomy, is originally derived from the need for scientific classification of species. It now extends to other sciences, including human sciences, information sciences and computer science. Sometimes we call it "taxonomy" to describe the result of a taxonomic activity, that is to say a classification.
The traditional classification is based on a fixed hierarchy of categories (taxon ranks), defined as follows:
Reign (or Kingdom) (there are currently six) → Division (or phylum) → class → order → family → gender → species.
Answer:
b. x chromosome inactivation
Explanation:
As you know, female cats have an x chromosome inherited from their mother and an x chromosome inherited from their father. After these two chromosomes are inherited and determine the sex of the cat, one of them will be disabled at some point in fetal development. Inside the X chromosome is the gene that determines the coat color of cats, when one of the two x chromosomes is deactivated, the other x chromosome will have all of its cells activated. In this case, if the activated chromosome is the one that has genes for the "cheetah" pattern of the coat color, all the descendants of this female cat also have the same coat.
The answer to this is Quaternary.
