Answer:
Cross the flies with the flies from another population
Explanation:
Inbreeding is the mating between the closely related individuals of a population. Inbreeding reduces the viability of the progeny over a generation since it increases homozygosity. When the flies of a small population interbred over generations, the increased homozygosity reduces the viability of the flies. To counteract it, one should mate these flies with the flies from another population. This would increase heterozygosity and thereby would increase the survival and fitness of the progeny.

One can stimulate a baby to breathe by slapping  his butt or by flicking the soles of his feet. This is normally done in order to stimulate a baby to take his first breath through the process of crying. Crying will force the baby to take his first breath and at the same time, it will enable the lungs and the airways to be cleared of liquid substances.
