What is Phenocopy? Phenocopies (translated as “false copy”) are over-dominant characteristics of an organism, which are artificially given a certain meaning that has no connection with the physiological properties of a given organism or its adaptability to the environment. Such reproduction cannot be called sexual or asexual. This is the result when the vitality and properties of one organism influence the life of another, and these influences can be quite diverse: up to the point that the set of chromosomes in the recipient - a plant or animal - is modified. Heritability of phenocopies As a rule, phenocopies are of a genomic-cytoplasmic nature: they constitute the phenotype of the descendant. The heredity of such traits depends on the properties of the gonad (gametes). The nature of phenocopic features is anomalous; the very essence of this phenomenon means that the generic nature of certain descendants ceases to be uniquely identified; the phenomenon of independence of generic status from generic status arises. Based on what we need to start from to explain the phenocopic phenomenon, we can assume that the problem is not directly related to the biological nature of the population or even the species, but is purely genetic. After all, each phenotype has its own genetic apparatus. Phenotypic duplication is based on the phenomena of interaction of the phenome with the genome and cell nucleus. Manifested traits are combinations of genes. Plants and animals with the same set of chromosomes that determine one genotype have differences in phenotype. They are detected for various reasons: the age of individuals, gender, subspecies, their living conditions. For example, naked walnuts (rounded fruits)
