Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In humans, the mitochondrion is only inherited through the ____
A
Mother
B
Father
C
Godmother
D
Godfather
Explanation: 

Detailed explanation-1: -In nearly all mammals, this mitochondrial genome is inherited exclusively from the mother, and transmission of paternal mitochondria or mitochondrial DNA (mtDNA) has not been convincingly demonstrated in humans.

Detailed explanation-2: -Our mitochondrial DNA accounts for a small portion of our total DNA. It contains just 37 of the 20, 000 to 25, 000 protein-coding genes in our body. But it is notably distinct from DNA in the nucleus. Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.

Detailed explanation-3: -The nucleus harbours most of our genes, tightly packaged into 46 chromosomes, of which half are inherited from our mother’s egg and half from our father’s sperm. By contrast, mitochondrial DNA (mtDNA) was thought to derive exclusively from maternal egg cells, with no paternal contribution1.
