Which of the following is true about natural selection? A. Natural selection acts upon individual organisms by changing their genetic code through a process known as gene flow. B. Natural selection causes changes in populations because of the differential reproductive success of genetically varied individuals. C. Natural selection acts upon asexually reproducing populations that lack genetic variation among individual organisms. D. Natural selection causes changes in individual organisms because individuals adapt during their lifetime to better suit their environment.

Natural selection causes changes in populations because of the differential reproductive success of genetically varied individuals. That's the correct answer, for the selections that you have provided. Therefore, the correct answer in the selections you have provided would be letter B above; that's the true one!

The following is true about natural selection is B. that Natural selection causes changes in populations because of the differential reproductive success of genetically varied individuals.

What is the gene flow?

Gene flow is the movement of genes in and out of a population. Such movements can result from the movement of individual organisms breeding in new populations, or the movement of gametes (for example, as a result of pollen movement between plants).

Genetic variation that alters genetic activity or protein function can introduce a variety of traits into an organism. Ultimately, natural selection works only by differences in reproductive success, Differences in mortality can be selective, but only to the extent that they make differences between individuals.
