In a population of wild bees, a mutation resulted in slightly larger wingspan in some of the bees. This larger wingspan made the bees more efficient in their flights to flowers to collect nectar. Thus, these bees became more successful. This trait was passed on to offspring, and eventually the larger wingspan variety of bee replaced their smaller-winged relatives completely.
-The larger wingspan could be called
A) an adaptive trait
B) genetic variability
C) a heritable trait
D) an adaptive trait and a genetic variability
E) a heritable trait, an adaptive trait and a genetic variability

The larger wingspan is a heritable trait because it was passed on to offspring. It is also an adaptive trait because it increases the efficiency of their flight to collect nectar. Additionally, it is a genetic variability because it is a result of a genetic mutation that caused the variation in the population. Therefore, the best choice is E, which includes all three options.
