Which term describes the process that involves reproduction of two different organisms resulting in two haploid cells, each with half the DNA of each parent organism?
That would be meiosis. Meiosis is for gametes (germ/sex cells). It will start off with one diploid cell then as it goes through PMAT I it will become two diploid cells and at the end of PMAT II, it will be two haploid cells each = a total of four haploid cells
