Haploid sperm and egg are produced via meiosis. What process is responsible for producing the 2N zygote?
kirza4 [7]

The answer is fertilization.


Fertilization is the process in which two haploid gametes fuse to create one diploid cell. <span>In this process, male sperm fuses with female egg which creates a zygote. Since they are haploid (n), after fertilization, they will create the zygote which contains chromosomes from the sperm and chromosomes from the egg. The zygote, thus, has two sets of chromosomes, so it is diploid (2n).</span>

Evolution acts upon the population of organisms and not on each individual organism
Marina86 [1]

Evolution can be defined as the process of changes in the genetic pool of a population over time. The process of natural selection operates the evolution of any population. Evolution acts upon a whole population instead upon on single individual. A single individual doesn't evolve, instead ratios of the genetic types within a population changes when it is evolving, and eventually, complete evolution occurs.

Hence, the given answer is 'true'.
