Question

The process of reproduction which involves only a single parent to form an individual is called as:
A. Sexual reproduction
B. Asexual reproduction
C. Isogamy
D. None of the above

Answer 1

Hint:- Reproduction is the biological mechanism in which parents (existing organisms) produce new individual organisms also called offspring. Reproduction is a fundamental feature of all known living organisms as each organism exists in this world only as of the result of reproduction.

Complete step-by-step solution:-There are mainly two types of reproduction i.e, asexual and sexual. Asexual reproduction is a form of reproduction that does not involve gametes fusion or the change in the number of chromosomes. Only a single parent (unicellular or multicellular organism) divides itself and gives rise to offspring that inherit the genes of that parent. Examples of asexual reproduction are budding, fragmentation, binary fission, and vegetative propagation.
Sexual reproduction is a form of reproduction with a complicated life cycle in which a gamete with a single set of chromosomes combines with another to produce an organism made up of cells with two sets of chromosomes. Examples of sexual reproduction are plants and many animals including human beings.
 Isogamy is a form of sexual reproduction involving gametes of identical morphology, differing in general only in the expression of alleles in one or more regions of the mating type. They are labeled as "male" or "female" as both gametes look alike. Therefore the correct answer is B i.e, ‘Asexual reproduction’.

Note:- The purpose of reproduction is to ensure that the species of plant or animal does not vanish from the Planet. This mechanism is very important for sustaining ecological stability and for the continuity of life on Earth. If no reproduction had occurred, all the species may have been extinct.
