Question

Which of the following statements regarding the asexual reproduction is incorrect?
(A) Both mitotic and meiotic division occurs.
(B) It does not contribute to evolution and speciation.
(C) It is uniparental and usually occurs in unicellular organisms.
(D) There is no variation and the off springs have the same phenotype and genotype.

Answer 1

Hint: Asexual reproduction is defined as the creation of offspring by a single pair, whether or not gamete development is involved. As a result, the children born not only resemble one another but also are exact replicas of their parents. Asexual reproduction involves only mitotic division.

Complete Step by Step Answer:
Because asexual reproduction is less complicated and only involves one parent, it is generally faster than sexual reproduction. In sexual reproduction, gametes initially develop before joining together to produce a diploid zygote. Since only one parent is involved in asexual reproduction and there is no fusion of male and female gametes, the offspring are genetically identical to their parents. Thus, the offspring is a clone of the parent. Asexually reproducing organisms exhibit very little or no variation. This is so because there is only one parent involved in asexual reproduction. Consequently, the children born are nearly clones.

The minute errors in DNA copying are the cause of the tiny variances. Given that only one parent is involved in the process and that the offspring are either genetically identical to one another or have a comparable genetic make-up, uniparental reproduction is also known as asexual reproduction.

So, option (A) is correct.

Note: Asexual reproduction does not require male and female individuals, and there is no fusion of gametes, whereas sexual reproduction involves the joining of male and female gametes.
