You wish to create a mutation in which you prevent access of rna polymerase to the gene. Which region of a gene would you target
Alexus [3.1K]

Answer:

The promoter region/sequence

Explanation:

Promoter sequences/region is where the transcription factors and RNA polymerase must attach before the gene can be transcribed. SO if we mutate this sequence, the transcription factors and RNA polymerase won't recognize it thus would not attach and transcribe the targeted gene.

Many closely related species of ducks have different courtship dances that are performed to solidify a pair-bond. If you were to
damaskus [11]

Answer:

I would expect to see a new phenotype in which the new duck hybrid species would express a new mixed courtship dance with the behaviors of both parentals.  

Explanation:

The cross between both parentals, each from different species, might produce a new phenotype that exhibits both parental dances. The new dance might be considered a hybrid of the parental dances.

Genetically speaking, we can think that there is a gene codifying for the courtship behavior in one species and another gene expressing a different courtship behavior in the other species. This cross´ product would be a hybrid species that exhibits a part of both parentals´ behaviors.
