Reproduction
The term reproduction is a biological process that means to reproduce. It is a process by which an organism reproduces an offspring that is biologically similar or identical to its parents. Reproduction accredits and ensures the continuity of species, generation after generation, and is the main character of life on earth.
Types of Reproduction:
There are two types of reproduction such as:
Asexual Reproduction:
It is the production an offspring by a single parent beyond the formation and fusion of gametes. The young one obtains all its genes from one parent, so are identical.
Sexual Reproduction:
Sexual reproduction is mostly biparental, includes the formation of meiosis gamete usually fertilization also, instigates genetic variation in the offspring, and plays a role in the evolution of species, found in higher plants and animals.
