Question

Define clone.

Answer 1

Hint:During the process of sexual reproduction, fertilization results in single-celled zygote which includes genetic material from both gametes. Genetic recombination is defined as the process where genetic material (DNA) joins up so that homologous chromosome sequences are aligned with each other. This process is completed by an exchange of genetic information.

Complete answer:
>Offspring do not contain exact copies of parental DNA. Cloning is defined as the process of producing genetically identical individuals of an organism either naturally or artificially.
>In nature, clones occur through asexual reproduction have been produced by organisms.
>The term clone, coined by Herbert J. Webber, springs from the traditional Greek word "twig", pertaining to the method whereby a replacement plant is often created from a twig.
>In botany, the term lusus was traditionally and earlier used.
>In horticulture, the spelling clon was used until the 20 th century; the ultimate e came into use to point the vowel may be a "long o" rather than a "short o". Since the term entered the favoured lexicon during a more general context, the spelling clone has been used exclusively.
>These clones have identical DNA.

Note:The offspring’s that are produced and are developed as a result of asexual reproduction are not only identical to one another but are also they are exact copies of their parent. So, such individuals are termed as clones. The offspring, thus formed, do not possess exact copies of parental DNA but somewhat identical copies. These are formed without fusion of gametes.
