Description : Does a genotype have to display a phenotype?
Last Answer : I am no genetic expert, but I believe this can happen. For example, two humans can have brown eyes. This would be their phenotype. One person could have an allele for brown eyes and ... so obviously this is the phenotype that would be expressed. They have the same phenotype and different genotypes.
