A Cell Can Contain Many Mitochondria, Each with Several Copies

question 79

Multiple Choice

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.
