Answer:
Speciation occurs at terminal population groups
Explanation:
A ring species represents a group of organism that has moved beyond a geographic barrier to produce a ring shaped distribution. This population is contiguous and there exists no barrier to gene flow anywhere in the ring except at the terminal populations.
Speciation is demonstrated in the terminal population has become sympatric and it does not interbreed even if they are connected by chain of intergrading or interbreeding populations
The Prader-Willi syndrome (PWS) is due to the lack of expression of paternal genes of the 15q11-q13 region. It usually occurs sporadically, although some family cases have been described (<1%). Approximately 70% of cases are produced by deletions of paternal origin in the 15q11-q13 region. 28% of cases are due to maternal uniparental disomy and less than 2% are caused by imprinting alterations. A geneticist studying prader-willi syndrome should focus on chromosome 15, its structure or changes in the number, these anomalies are also related to other syndromes such as: Bloom Syndrome, Breast cancer, Isovaleric acidity among others.

In eukaryotes, it should be noted that the ATP synthase is located in the inner membrane of mitochondria
<h3>What is ATP synthase?</h3>
The ATP synthase is the mitochondrial enzyme that is localized in the inner membrane, where it catalyzes the synthesis of ATP driven by a flux of protons.
It should be noted that the absence of ADP, the ATP synthase will stop functioning and when this happens, the movement of protons back into the mitochondrion also stops.
The goal of aerobic respiration is simply to derive energy from macromolecules like carbohydrates, proteins, and fats to carry out various energy-requiring processes. Here, the chemical energy is trapped in the form of ATP. It should be noted that aerobic cellular respiration takes place in the cytoplasm and mitochondria.
