Which terminology is considered to be correct when two genotypes produce the same phenotype due to different environments?

When two genotypes produce the same phenotype due to different environments, it is known as Phenocopy.
A phenocopy is a phenotypic trait or disease that resembles the trait expressed by a particular genotype, but in an individual who is not a carrier of that genotype.
The phenocopy induced by the environmental conditions mimics the phenotype produced by a gene. For example, a phenocopy is observed in Himalayan rabbits which have a white-coloured coat along with a black tail, nose, and ears when raised in moderate temperatures.
