What Type of Inheritance is Observed with Extranuclear DNA

Question

What type of inheritance is observed with extranuclear DNA?
A) mendelian inheritance
B) sex-linked inheritance
C) paternal inheritance
D) Inheritance patterns are based on cytoplasmic inheritance.

Accepted Answer

Inheritance patterns for extranuclear DNA, which is located in the cytoplasm of the cell, are based on cytoplasmic inheritance. This type of inheritance is determined by the maternal genome, as the majority of cytoplasmic DNA is inherited from the egg cell. This means that traits determined by extranuclear DNA will only be passed on by the maternal line.
