Reproduction is the biological process by which living systems replicate new individual systems which are similar to themselves. All known life, including a single cell, a multicellular animal or plant organism, has the ability to reproduce offspring. The most important thing of reproduction is to transmit hereditary material to their offspring by diversiform strategies and processes. Reproduction can be classified into two fundamental types, including asexual reproduction and sexual reproduction. The Asexual reproduction refers to the process that an organism reproduces offspring itself, which needn’t involvement of another organism. This type of reproduction is found in both single-cell organisms and multicellular organisms (such as some plants). In sexual reproduction, gametes from two different specialized organisms are required. Each gamete contains half the number of hereditary material in normal cells. The combination of two gametes is called fertilization and forms a zygote. Thus offspring from sexual reproduction contains genetic characteristics from the two parents. Both asexual reproduction and sexual reproduction have advantages and disadvantages and some organisms utilize both of them.
The reproduction involves with complex organs and elaborate hormonal mechanisms. As a primary manufacturer of recombinant proteins, Creative Biomart provides molecular tools and proteins of several sources, grades and formulations for reproduction research applications.
