Question

Cloning is a mode of_____ reproduction.

Answer 1

Hint: Process of generating a genetically identical organism or copy of organisms in which, if the haploid nucleus of the egg cell is replaced with a diploid nucleus, form the cell of an individual of the same species.

Complete answer:
To answer this question you must know about cloning.
Cloning is a method used to make a clone or identical copy of an entire multicellular organism. Cloning happens often in nature –for example, prokaryotic organisms such as bacteria create genetically identical organisms using binary fission and eukaryotic organisms all cells undergo mitosis, such as skin cells and cell lining the gastrointestinal tract are clones; the only exception is gametes which undergo meiosis and genetic recombination.

Parthenogenesis, or virgin birth; is a form of asexual reproduction. An example of parthenogenesis occurs in species in which the female lays an egg. If the egg is not fertilized, it remains a haploid egg and develops into a male. The unfertilized egg is called parthenogenetic in which cells replicate themselves without any genetic alteration or recombination.

Reproductive cloning of dolly, the sheep dolly the first mammals to be cloned. To create Dolly, the nucleus was removed from a donor egg cell and the second sheep was nucleus than introduced into the cell, which helps to divide to the blastocyst stages before being implanted in a surrogate mother.

Therefore cloning is a mode of asexual reproduction as in this case embryo develops without fertilization of the eggs.

Note: The first cloned animal was dilly, a sheep who was born in 1996. The success rate of reproductive cloning at that time was very low. Dolly was alive for seven years and died of respiratory complications. Now reproductive cloning has become successful, but still has limitations as cloned individuals often exhibit facial, limb, and cardiac abnormalities.
