How could farmers increase the yields of their crops without using genetically modified organisms?

Temperature, light, and carbon dioxide levels affect photosynthesis. Farmers use fertilizers, pesticides, and biological control to increase crop yields.

Explanation:

I hope you know that GMOs are actually a good thing for this planet. They have been known to decrease the need for pesticides. Also, the growing population will require more food as time goes on. GMOs can prevent world hunger in the next hundreds of years.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?
