Which includes the physical characteristics of an organism?
gene
allele
genotype
phenotype

In genetics, we use the term phenotype that refers to the physical characteristic of the organism.

Further Explanation:

Genetics is the term which is used to refer to the study of inheritance. Basically, genes, that are present on the DNA, get inherited from one generation to the subsequent one. Genes are responsible for encoding the protein and exhibiting all kinds of activities occurring in the living system. Genes are present in its alternative form, known as an allele, on the homologous chromosome.

A genotype is a term that is used to refer to the genetic constitution of the organism. Genotyping of the organism is important for studying polymorphism in the population.

The phenotype of the organism tells about the physical appearance of the organism. From the phenotype of the organism, one can decipher the genotype of the organism.
