Distinguish between dimorphic, polymorphic, and continuously variable traits.
jolli1 [7]

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.
