The video tutorial explains sexual reproduction, a biological process involving two individuals, male and female, of the same species to produce new offspring with shared traits. It highlights the two main processes: gamete formation and fertilization. Gametes are formed through meiosis, containing half the number of chromosomes. Fertilization occurs when male and female gametes merge to form a zygote, restoring the original chromosome number and combining genetic material from both parents. The zygote grows into a new individual with traits from both parents.
