Answer:
b. transcriptional control of gene expression.
Explanation:
The binding sites of transcription factors (enhancers and silencers) can activate or deactivate, respectively, a gene in specific parts of the body.
Some genes must be expressed in a part of the body. For example, if you need to activate a gene in the spine, skull and toes, but not in the rest of the body, how can transcription factors do this task?
As a gene of this type of pattern it can have several enhancers or silencers, where each one can activate or repress the gene of a specific type of cell or part of the body, joining transcription factors that occur in that specific part of the body.

I think the best answer would be culture. This is because all these aspects would motivate people going to the weight loss canter as well as health club in an attempt to live responsibly and healthy. In turn this would promote the business of those who own the centers as many individuals have adopted those aspects.
So first off homozygous means that both alleles are the same
If coiling to the right is dominant and to the left is recessive let capital c (C) represent right coiling and let lower case c (c) represent left coiling.
The female who is homozygous recessive must have both recessive alleles
The male who is homozygous must have two dominant alleles
So the cross will be between a CC and a cc
So we set up a Punnett square
We take a look at all the combinations and arrange them
So we find that there is a 25% chance of the offspring having left coiling
