Detailed explanation-1: -At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

Detailed explanation-2: -Each daughter cell will have four chromosomes after completion of the division.

Detailed explanation-3: -All organisms have chromosomes, but some have more than others. While human cells have a total of 46 chromosomes, the cells of a goldfish have 100, and a dog has 78.

Detailed explanation-4: -Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.
