Mutation
Explanation:
The main cause of variation within a population is usually through genetic mutation.
Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.
Most times, environmental influences are paramount to causing genetic mutation within a population.
Other times, it might be due to competition and some other internal factors.
Mutation can be transferred from parents to offspring in most cases.

Answer: the question is not detailed enough
Explanation:
For instance if the genotype of the parent is AS and AS there would be a cross breeding of the genotype to give the First filial generation (F1) then any other crossbreeding is known as the F2

In the given situation the appropriate step would be to give sets of 5 back slaps and 5 chest thrusts.
If one finds an infant choking, and he or she is not responding, then first kneel or sit with the infant in the lap. Hold the infant with the face down and resting on the forearm, with the head slightly lower in comparison to the chest. After that, there is a need to apply 5 sets of back slaps and 5 sets of chest thrust.
Clearing a substance from a responsive infant's airway needs a combination of chest thrusts and back slaps. However, abdominal thrusts would not be appropriate.
