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.

To determine if you have identified a functional open reading frame (orf), you should have found __________ within the sequence.
HACTEHA [7]

The answer is a start codon. An open reading frame is a region of DNA with a span of nucleotides beginning with a start codon (usually ATG) and ends with a stop codon (usually, TGA, TAG, TAA). An open reading frame when translated, codes for a full functional protein hence can be used to predict genes.
