When two parents are involved in reproduction, the method is called sexual reproduction. The male and female gametes fuse during fertilization to produce zygote. The zygote subsequently develops into an embryo which further develops into a new individual.

Sexual reproduction involves two parents, each contributing specialized sex cells (sperm from males and eggs from females) containing half the genetic material. These cells combine during fertilization to form a new organism with a unique mix of traits from both parents. This method promotes genetic diversity among offspring, allowing for adaptation to different environments. Unlike asexual reproduction, sexual reproduction creates varied offspring, ensuring species resilience and evolutionary development through diverse genetic combinations.
