The ovaries and testes produce haploid gametes by meiosis. During fertilization. These gametes, sperm and ovum, fuse, forming a diploid zygote. This starts the human life cycle. The zygote (fertilized egg) Develops into an adult organism. Generates all of the somatic cells of the organism.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
