Question
When two or more different looking phenotypes occur in the same population of a species, then it is called:
- Gene expression
- Gene linkage
- Mutation
- Polymorphism
Hint:
Polymorphism, also known as an alternative phenotype, is the occurrence of two or more distinctly different morphs or forms in a population of a species.
The correct answer is: Polymorphism
- Polymorphisms, which occur when different alleles of the same gene are expressed by different members of a population, are common.
- Polymorphic populations are those that have two or more versions of a particular trait.
- Population variation also referred to as the distribution of phenotypes among people is impacted by a variety of variables, including the genetic makeup of the population and its environment.
- It's crucial to comprehend the origins of phenotypic variation in populations in order to predict how they will change in response to various evolutionary pressures.
