b. one of the various forms of a gene
c. the set of chromosomes
d. the genetic constitution of an individual
e. the set of chromosomes including the sex ct not counting the sex chromosomes

a. the result of an individual's genetic constitution

Explanation:

Phenotype is the morphological expression of genotype. The genetic constituent of an individual is known as genotype. Genotype determines the genetic traits and imparts specific features of the organisms which constitute the phenotype of the organism.

The phenotype of the organisms depends on the type of the alleles of the genes present in the genome of the organisms.

For example, a human with genotype "ii" has blood type "O". Here, "ii" is the genotype that is responsible for phenotype "O blood type".

On the other hand, a human with genotype "IAIA" has blood type "A". Here. "blood type A" is the phenotype.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
