1. Fertilization is the fusion of sperm and egg.
2. Gametes are reproductive cells (sperm and eggs).

9. The zygote would have double the normal number of chromosomes, likely causing problems.

10. If gametes weren't haploid, the zygote would end up with too many chromosomes, leading to developmental issues or failure.
