Scientists Studying Speciation Often Look at Both Nuclear DNA and Mitochondrial

Multiple Choice

Scientists studying speciation often look at both nuclear DNA and mitochondrial DNA. Why is the genetic information obtained from mitochondrial DNA different from information obtained through nuclear DNA in sexually reproducing species?

A) In most organisms, mitochondrial DNA is inherited from the male, while nuclear DNA is inherited from both parents.
B) Mitochondrial DNA has a very low rate of mutation and is highly conserved, while nuclear DNA changes rapidly.
C) In most organisms, mitochondrial DNA is inherited from the female, while nuclear DNA is inherited from both parents.
D) Mitochondrial DNA only has one set of chromosomes, while nuclear DNA typically has multiple sets of chromosomes.
