ASEXUAL REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which statement best describes the process of asexual reproduction?
A
new organisms are usually genetically identical to the parent
B
the reproductive cycle involves the production of games
C
nuclei of sex cells fuse to form a zygote
D
it involves the production of genetic copies
Explanation: 

Detailed explanation-1: -Answer: The best statement that describes the process of asexual reproduction is (4) it involves the production of genetic copies. Asexual reproduction is a type of reproduction that involves the production of offspring without the involvement of fertilization or the combination of sperm and egg.

Detailed explanation-2: -Parthenogenesis. Parthenogenesis is a form of asexual reproduction where an egg develops into a complete individual without being fertilized. The resulting offspring can be either haploid or diploid, depending on the process and the species.

Detailed explanation-3: -Answer. Explanation: The clone is genetically identical to its parent. Asexual reproduction requires only one parent and produces identical offspring, while sexual reproduction requires two parents and produces non-identical offspring.

Detailed explanation-4: -Mitosis is a process where one cell divides into two cells (Fig. 2.46). Chromosomes in the original cell are duplicated to ensure that the two new cells have full copies of the necessary genetic information. The process of mitosis generates new cells that are genetically identical to each other.

Detailed explanation-5: -Asexual reproduction is a form of reproduction in which the offspring produced is exactly similar to the parent. Also, neither there is formation of two different gametes, nor there is an involvement of two different sexes. In case of unicellular organisms, mitosis is a mode of asexual reproduction.
