Question

which parent is each of the following inherited from?
drag each item on the left to its matching item on the right.
neither parent
only mother
only father
both parents
nuclear dna
none
mitochondrial dna

Explanation:

• Nuclear DNA: Each parent contributes half of the nuclear DNA. So it is inherited from both parents.
• Mitochondrial DNA: Sperm does not contribute mitochondria to the zygote. Mitochondria (and thus mitochondrial DNA) are inherited from the mother only.
• "None" is not a valid biological inheritance category for DNA from parents in this context.

Answer:

• nuclear DNA: both parents
• none: neither parent
• mitochondrial DNA: only mother
