In an animal, how is the DNA from this organelle inherited?
1 answer
In animals, the DNA present in the mitochondria is inherited maternally. This means that the mitochondrial DNA (mtDNA) is passed down from the mother to her offspring. During fertilization, the sperm contributes only nuclear DNA to the resulting zygote, while the egg contributes both nuclear DNA and mitochondrial DNA. As a result, all the mitochondrial DNA in an individual is derived from their mother. This pattern of inheritance is referred to as maternal inheritance or matrilineal inheritance.
