Drosophila females are capable of storing sperm and using it to fertilize eggs long after mating. How might this present a problem for a geneticist?

#Unit 8. Inheritance Biology

IN ORDER TO DESIGN A SPECIFIC CROSS, FEMALES MUST BE PREVENTED FROM MATING WITH ANY OTHER STRAIN OF MALES.
This allows Drosophila females to "select" sperm from the stronger male.
Individual offspring from these females may have more than one father.
This should not present a problem for a geneticist; it is merely a reproductive advantage to the fly if the population size is low.
