Hi there!
Reproduction is the process of producing new organisms from the parent.
- An offspring is reproduced through 2 methods - sexual & asexual method.
- In the asexual method, only one parent is needed to reproduce an offspring. It can be through the form of budding, binary fission, fragmentation, parthenogenesis etc. It's usually used in the case of an unicellular organism. However methods like regeneration is used in reptiles & vegetative propagation is used in plants.
- In the sexual method, 2 parents are required to create an offspring. The zygote is formed from the fusion of the male & female gamete which in turn changes to an embryo to form a fully developed child in a matter of time. Development of the child in humans inside the mother lasts for about 9-10 months.
