👉 Polyphagism is a type of genetic variation in which an organism has more than one type of gene. This can occur when a gene from one sex (male or female) is expressed in both males and females, leading to a combination of traits that are not typically found in each individual but do exist within the same species. The term "polyphagism" refers to this phenomenon in which organisms have more than one type of gene, typically involving multiple traits at different levels of expression.
