Answer:
the population is polymorphic.
Explanation:
Polymorphism is the discontinuous genetic variation that leads to the production of varying unique kinds or forms of individuals within the population of an individual species.
Take for instance, allelic polymorphism is seen in the presence of multiple alleles that is produced within the members of an individual species as in peppered moths, human blood groups, and two-spotted ladybugs.
We have different causes of polymorphism: polymorphism can be sustained by an equity among variation developed by new mutations and natural selection. Genetic variation might be due to frequency-dependent selection.
