Question

Cytoplasmic inheritance is also called
a. Maternal inheritance
b. Clonal inheritance
c. Cytoplasmic association
d. None of the above

Answer 1

Cytoplasmic inheritance is also called Extranuclear inheritance and it is defined as the transmission of genes that occur outside of the nucleus. It is found to occur in the cytoplasmic organelles example in organelles such as mitochondria and chloroplasts.

Complete answer:

Option A - Maternal inheritance
We can define it as the passing of genetic material (cytoplasmic) present in organelles of mitochondria and chloroplast to the offspring. This inheritance occurs from the mother to its offspring.

Option B - Clonal inheritance
We can explain it as a type of inheritance that occurs in bacteria in which a group of cells are descended from bacteria and are genetically identical to it. As a result of this inheritance, the resulting products are exact clones that’s why it is called Clonal Inheritance.

Option C - Cytoplasmic association
It is defined as the association of different constituents of cytoplasm to form a cell a prominent identity in an organism. The constituent parts of cytoplasm such as cytosol, cell organelles, and filaments play an important role in the association of cells to form an identity. It is an important association as constituents of the cell lie within the cytoplasm and to carry out different functions of cells.

Hence, the correct answer is option (A), Maternal inheritance.

Note: Cytoplasmic Inheritance as such is important in principles of inheritance and by this genetic material of the organelles is passed from mother to its offspring which makes its offspring carrying its genetic material and identical to its parent.
