Whats the process involving sexual reproduction?
http://en.wikipedia.org/wiki/Sexual_reproduction
Sexual reproduction is a complex process that involves the fusion of specialized cells called gametes, typically from two individuals of the same species. Here's a summary of the process:
1. Gamete production: Both males and females produce gametes. In males, specialized cells called sperm are produced through a process called spermatogenesis. In females, specialized cells called eggs or ova are produced through a process called oogenesis.
2. Mate selection: In many sexually reproducing species, individuals must find a suitable mate in order to reproduce. This can involve various forms of courtship behavior, displays, or other mechanisms that allow individuals to signal their availability and attract potential mates.
3. Fertilization: Once a mate has been chosen, the male gamete (sperm) is transferred to the female reproductive system through mating. This can occur internally or externally, depending on the species. Fertilization takes place when a sperm cell fuses with an egg cell, resulting in the formation of a zygote - a single-cell organism with a complete set of genetic material from both parents.
4. Development: After fertilization, the zygote undergoes a series of cell divisions and transformations. This process, known as embryogenesis, leads to the development and growth of a new organism. The details of development vary greatly among different species.
5. Birth or hatching: Eventually, the developing organism is ready to leave the parent's body. In mammals, this is known as birth, while in birds or reptiles, it is called hatching. The new organism, called a neonate or offspring, is now able to survive and grow independently.
It is important to note that the process of sexual reproduction can be quite diverse among different organisms, and the above steps only provide a general overview. Detailed intricacies and variations exist within different species, including additional reproductive strategies, such as internal fertilization, egg laying, live birth, and various forms of parental care.
