Answer:
Variable expressivity, Incomplete penetrance, Phenocopy, Genetic heterogeneity
Explanation:
Phenocopy: When an environmentally caused phenotype mimics one that has a genetic basis. The variation in phenotype caused by environmental conditions exists in such a way that the organism's phenotype matches a phenotype which is determined by genetic factors.
Variable expressivity: When a characteristic is subject to a range in severity or degree of expression in the phenotype.
Genetic heterogeneity: When the same phenotype/disease can be caused by different genes.
Incomplete penetrance: When individuals have a genotype that specifies a particular phenotype but that phenotype does not develop.
Voltron is not a subatomic particle
It is in the nature of the animal to act as how their biological parents did. Genetically something in the brain keeps the "tradition" ongoing.
