A Cell Can Contain Many Mitochondria, Each with Several Copies

A cell can contain many mitochondria, each with several copies of its genome. Assume 50% of the mitochondria in a human egg are healthy, whereas the other 50% harbor a defective gene that leads to poor function. If this egg is fertilized, then the probability of the resulting child showing signs of defective mitochondrial function:

A) will be 50%.
B) depends on if the healthy version of the gene is dominant.
C) depends on if the mitochondria from the sperm can compensate.
D) can be determined by using the Punnett square.
E) cannot be determined because, unlike nuclear division, mitochondria do not segregate as evenly to descendent cells.
