Extrachromosomal inheritance involves genes passed on by the mother's __________.
A
chromosomes
B
mitochondria
C
ribosomes
D
Golgi bodies
E
smooth ER
Verified step by step guidance1
Understand the concept of extrachromosomal inheritance, which refers to the transmission of genetic material that is not located on the chromosomes within the nucleus.
Recognize that mitochondria are organelles within the cell that contain their own DNA, separate from the nuclear DNA. This mitochondrial DNA is inherited exclusively from the mother.
Consider the role of other organelles listed in the options: ribosomes, Golgi bodies, and smooth ER, none of which contain their own DNA for inheritance.
Identify that the mitochondria are responsible for extrachromosomal inheritance due to their unique genetic material passed down maternally.
Conclude that the correct answer to the problem is mitochondria, as they are the organelles involved in extrachromosomal inheritance.
