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.
Answer:

D(appearance of secondary sex characteristics)
Explanation:
Kingdoms are Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia.
I'm not sure if these 6 kingdoms I listed are one of the"which of the following"options you asked for so I hope it helps.
Answer:
idk if it's good..
Explanation:
The dark-colored mice arose in the population at location A by random mutation. ... advantage over light-colored mice in that environment. • Over time, dark-colored mice became more common at location B because more of their offspring survived. to reproduce and pass on their genes, including genes for fur color.
Answer:No
Explanation: there would not be a way to distinguish between Tt and TT without mating or DNA analysis because T is dominant in Tt, therefore has the same physical characteristics as TT.
