what is reproduction in biology



Why don't libraries smell like bookstores? Build-up the basic understanding from the NCERT textbook of class 12. ISBN 978-0-09-928375-1 [19] Venter plans to patent his experimental cells, stating that "they are pretty clearly human inventions". Whether or not there were several independent abiogenetic events, biologists believe that the last universal ancestor to all present life on Earth lived about 3.5 billion years ago. Flowers produce both female and male gametes. Reproduction, in a nutshell, is a methodology of continuation of life, which provides with suitable variations and chances of evolution in its course of occurring.

The first ones were likely in the form of sponges. The offspring is produced as a new individual organism from the parent(s). Also, because the process of gametogenesis is subjected to hormonal regulation which, in turn, is influenced by the emotional and social stability of a person, reproductive health in humans is wider filed of understanding and practice. The two broad categories of the process of reproduction are elaborated here as: a) Asexual Reproduction: The process of reproduction that occurs by a single parent. Sexual reproduction ensures a mixing of the gene pool of the species. Sexual reproduction, he argued, was like purchasing fewer tickets but with a greater variety of numbers and therefore a greater chance of success. It does not involve the process of meiosis and gamete formation.

Word origin: Latin re (again) + productio (production) Synonym(s): For human species to obviate extinction, reproductive mature adults should be producing viable offspring in order to continue the existence of the species and pass on genetic information from generation to generation. Mitosis occurs in somatic cells, while meiosis occurs in gametes. There are two forms of reproduction. The tutorials included here focuses on human growth and development.

The diploid stage is relatively small and short-lived compared to the haploid stage, i.e. Reproduction is the ability of living organisms to form new individuals of the same species from those already in existence.
