Becuase there is a broad range of phenotypes for human height, the trait is an example of a polygenetic (poly = many, genetic = of genes) trait.
Due to the vast variations of human height, the trait is clearly not purely dominant or recessive. A dominant trait is due to a dominant allele (variation of a gene) which completely masks a recessive allele. If only dominant and recessive height phenotypes existed, there would only be two heights observed in humans!
Since there is such a vast variation amongst human heights, the trait is an example of a polygenetic trait. Polygenetic traits are traits that are influenced by more than one gene at multiple loci (locations) on one or more chromosomes. This results in a continuous distribution of traits within a species. Other examples of polygenetic traits include skin color, hair color, and weight.
Answer:
B) For a gene under negative repressible control, a small molecule is required to prevent the gene's repressor from binding to DNA.
Explanation:
Operon is usually present in prokaryotes. It has a group of genes being transcribed under the same promoter. So the genes are expressed together when required. An operon can be under negative or positive control. It can further be inducible or repressible.
Under negative repressible control the operon is normally in working condition. Repressor protein is present but unable to bind to the operator. When a corepressor binds to repressor, it is activated and finally binds to the operator halting the transcription process. Hence the small molecule (corepressor) leads to binding of repressor to DNA and not the other way round. A small molecule is required to prevent the gene's repressor from binding to DNA in case of negative inducible operon.
Answer:
Disadvantageeous trait
Explanation
Since the moth is not high up in the food chain, it would want to hide from others by blending in with its surroundings rather than be easily seen as that would just make it easier for them to become easy prey for anything higher up in the food chain nearby.
