Answer:
Explanation:
My best bet is DNA methylation at the site of Tweedledum's leptin gene or Histone Acetylation at the site of Tweedledee's gene.
B/c DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. So this is probably repressing Tweedledum's leptin gene trancription which is not happening in Tweedledee.
Additionally, Histone Acetylation at site of Tweedledee's gene increases her trancription b/c Histone acetylation causes DNA to be more accessible and leads to more transcription factors being able to reach the DNA. Thus, acetylation of histones is known to increase the expression of genes through transcription activation.

The effects of electrical stimulation on the sciatic nerve may be observed by watching the nerve under a dissecting microscope. Electric stimulation therapy is a therapeutic treatment that applies electrical stimulation in treating muscles spasm and pain. An assortment of lower back problems can cause the pain that radiates along the sciatic nerve.
Answer:
The first one in the image :)
Explanation:
If its asexual then, only the same species will reproduce therefore making it reproduce only one species.
It'll be much cleaner for the environment.
