In humans, mitochondrial genetic disorders are inherited from only the mother. The severity of such diseases can vary greatly, even within a single family. What form of inheritance does this represent?.



Answer :

The form of inheritance represented by mitochondrial genetic disorders is cytoplasmic inheritance.

The cell contains several cell organelles like mitochondria, chloroplast, Golgi apparatus, endoplasmic reticulum, etc.

Among the organelles present inside the cell, mitochondria and chloroplast are the two organelles that contain their own DNA.

During fertilization, the fusion of sperm and the ovum takes place to form the zygote.

The majority of the cytoplasm present inside the zygote is from the maternal cytoplasm i.e, the ovum. The paternal contribution to the zygote’s cytoplasm is negligible.

Therefore, if any disorder occurs in the maternal mitochondrial DNA, it will get inherited by the offspring.

As the mitochondria are present in the cytoplasm of the cell, the inheritance of mitochondrial traits is known as cytoplasmic inheritance.

Hence, the form of inheritance represented by mitochondrial genetic disorders is cytoplasmic inheritance.
