Re: Mito inherited from father?

[Guest guest]

-I believe that mitochondria are inherited only from the mother.

http://www.mostgene.org/gd/gdvol10b.htm

Mitochondria are passed from generation to generation only through maternal

egg cells where they are abundant. Those present in sperm are

concentrated in the tail and do not contribute to the compliment of the

fertilized zygote. Molecular genetic tracking of polymorphic or variable

regions through families and even across the millenia of human evolution

confirm maternal inheritance of mitochondrial DNA.

CAN MUTATIONS IN THE MITOCHONDRIAL

GENES BE INHERITED?

The number of mitochondria in every cell of a person's

body varies from a few to hundreds. All of these mitochondria, and therefore

the DNA within the mitochondria, descend from the small number of

mitochondria present in the original egg cell at the time of that person's

conception. The sperm does not contribute any mitochondria to the baby.

Thus an individual's mitochondria are only inherited from his or her mother.

An abnormality in one of the mitochondrial genes can therefore be passed

by the mother in her egg cells. As most of the mother's egg cells carry the

same mitochondrial mutation, the risk of this mother having another affected

child with the mitochondrial disorder is high.

It would depend on if your problem is in your nuclear or your

mitrochondira dna.

My son's " defect " in nuculear from both his father and from me. His

mito are not getting the correct instructions on how to process. My

own and my husband's defects had to have come from one or the other

of our parents as we both have one bad gene.

I did hear of a mito passing down to a child this last year from the

father which they had thought was impossible.
