An individual inherits their mitochondrial DNA from their mother.
The little circular chromosome contained inside mitochondria is called mitochondrial DNA. These organelles are the heart of the cell and are present in all eukaryotic cells. The only way for mitochondria and their DNA to be transmitted from mother to child is through the egg cell.
Mitochondrial inheritance: The mitochondria in this particular type of inheritance have their own DNA. Only illnesses resulting from mutations in the mitochondrial DNA are solely passed down through mothers.
Because sperm contain few mitochondria and these break down after fertilization, an individual's mitochondrial DNA is solely acquired from the mother.

Answer:
sarcoplasmic reticulum deteriorates and ATP production is stopped
Explanation:
Rigor mortis is the third stage of death characterized by stiffening of joints and muscles in body. The stiffening occurs because muscles are not able to return to the relaxed state. There are two reasons for rigor mortis, depletion of ATP and increase in calcium concentration in cytosol. Due to these factors the actin-myosin crossbridge is not able to break and the muscles remain in contracted state.
Sarcoplasmic reticulum deteriorates and calcium is released into the cytosol. Sarcolemma ( covering of muscle fiber ) also breaks down releasing extra calcium into the cytosol. Calcium is responsible for formation of actin-myosin cross bridge and when its concentration increases the bridge is formed continuously leading to stiffening of muscles and joints.
