Answer:
An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes
Step-by-step explanation:
Each distinct genome underlies a unique epigenetic landscape (middle), which defines what cell phenotypes are possible (top). This allows both for cells with identical genomes to adopt distinct phenotypes, and also for cells with distinct genomes to identify identical phenotypes (left VS right)
