Phenotype of an organism is the result of

  • mutations and linkages

  • cytoplasmic effects and nutrition

  • environmental changes and sexual dimorphism

  • genotype and environment interactions

Solution

C.

environmental changes and sexual dimorphism

Phenotype is the observable characteristics or the total appearance of an organism. It is determined by its genes, the dominance relationships between the alleles and by the interaction during development between its genetic constitution (genotype) and the environment. 
Mutation leads to variation and linkage to store genatype. Cytoplasmic effect a nutrition generally do not determine the phenatype.
