Suppose a scientist engineered the mass movement of transposable elements in the genomes of a group of fruit flies, and then these flies had offspring.A control group of flies that were from the same genetic strain but had not had a mass movement of transposable elements also had offspring.The most likely result would be that the average survival rate of the experimental offspring would be _______ than that of the control offspring, and that the genetic variance in the experimental offspring would be _______ in the control offspring.
A) higher; greater than
B) higher; roughly the same as
C) higher; lower than
D) lower; higher than
E) lower; lower than

Transposable elements can introduce genetic mutations and variability. This increased genetic variance might lead to some offspring being less fit for survival, hence a potentially lower average survival rate. However, the genetic variance would be higher due to the introduced mutations and rearrangements in their genomes.
