Correct Answer: Option 3 gene combinations different from those of either parent.
Option 1 is incorrect because before fertilization, the egg cell and sperm cell both underwent cell division making them haploid containing only half of the original chromosome content. Hence, the number of chromosomes of the offspring is just the same as either parent. For the same reason, option 2 is also incorrect.
Since the half each parents' genetic material has been joined together, there is variation from the offspring and the parent. Therefore, option 4 is incorrect and option 3 is the correct statement.
