In some organisms, karyokinesis is not followed by cytokinesis as a result of which, multinucleate condition arises leading to the formation of syncytium. The perfect example for this is

Pick out the correct statements. 

I. Mitosis takes place in the somatic cells and meiosis takes place in the germ cells. 

II. During mitosis, the DNA replicates once for one cell division and in meiosis the DNA replicates twice for two cell divisions. 

III. Mitosis and meiosis occur both in sexually and asexually reproducing organisms.

While in mitosis, the daughter cells resemble each other and also the parent cell. In meiosis, they differ not only from parent cell in having half the number of chromosomes, but also differ among themselves qualitatively in general constitution due to
