The genetic material inherited in an organelle, such as a mitochondrion or a chloroplast, exhibits Extranuclear inheritance.
When DNA in cytoplasmic organelles is handed on to offspring, extranuclear inheritance occurs. Cytoplasm can be found in both sperm and ovum cells in humans. Most of the extranuclear DNA formed when the sperm and ovum combine belongs to the mother. The organelles in the fertilized cell expand and divide as the fertilized egg grows. As a result, each new cell receives mtDNA, which likewise divides and is passed on. As a result, each child inherits mtDNA from the mother. The identical procedure takes place in creatures with cells that contain chloroplasts.
Nuclear DNA differs greatly from extranuclear inheritance in several ways.
- Chloroplasts and mitochondria both store several copies of DNA. Additionally, the cytoplasm of every cell contains a number of each organelle, occasionally thousands.
- In a cell's cytoplasm, chloroplasts and mitochondria are dispersed at random. There is a random distribution of amount in both daughter cells after cell division, whether it be through mitosis or meiosis.

Explanation:
Clients like the client in the question given above, who is in a confused state, need to be addressed in a calm and reassuring manner and in easy to understand terms. This would enable the client to better understand his situation and allay whatever anxiety that might arise.

Question 12: A trait that benefits an organism's ability to survive and reproduce
The ductus arteriousus is a blood vessel that connects the pulmonary artery to the descending aorta. Otherwise known as the ductus Botalli, this structure pumps blood into the fetus' non-functioning lungs from the right ventricle. This blood vessel will close at birth and becomes the ligamentum arteriousum.
