Genotype
DEFINITION
IT IS THE GENETIC MAKEUP OF THE CELLS.
Phenotype
DEFINITION
IT IS PHYSICAL APPEARANCE OF ORGANISMS.
The Genotype, carried by all living organisms, holds the critical instructions that are used and interpreted by the cellular machinary of the cells to produce the r Phenotype of the organism.
Thus, all the physical parts, the molecules, cells and other structures, are built and maintained by cells following the instructions give by the genotype.

Answer:
The taxonomical classification of organisms follows this list of categories
Kingdom
Phylum
Class
Order
Family
Genus
Species
The number of organisms decrease from the top(Kingdom)to the bottom(Species).
Order Phylum is the answer
Answer:
The evolution of a species is driven by many evolutionary mechanisms two of which are: natural selection and the genetic drift.
The natural selection selects the species or the alleles which increase the reproductive success of the species in a given environment whereas the genetic drift cause evolution by randomly selecting the alleles based on the sampling error. The genetic drift selects the alleles or species by chance and not on the beneficial and harmful basis.
In the given question, If natural selection favours the one trait of the species on the basis if it provides fitness then it could result in a genetic drift of alleles of another trait as it is purely based on the chance.
