As population density increases, competition increases because there are more organisms competing for the same number of resources
Dimorphic, polymorphic, and continuously variable traits are distinguished as follows:
- Dimorphism is the condition of those<em> species</em> of animals or plants that exhibit two anatomical aspects or two different forms.
- When talking about polymorphisms in genetics, reference is made to the different variations that may exist on the DNA of the same gene.
- Continuously variable traits are those that show a continuous distribution of phenotypes.
Therefore, we can conclude that dimorphism is a polymorphism with only two forms, the polymorphism is any stable change of the DNA fixed in the population and in continuously variable traits the phenotypes show a continuous series and cannot be easily grouped.
