Question

Assertion: Gametes are formed independently either from diploid or haploid parents. Gametes are always haploid.
Reason: In diploid parents, gametes are formed through mitosis and meiosis while in haploid parents it occurs through meiosis.
A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
C. Assertion is correct but Reason is incorrect
D. Both Assertion and Reason are incorrect

Answer 1

Hint: Gametes can be defined as a specific kind of cells that are concerned with carrying out reproductive processes within the organism. Both male and female individuals produce specific kinds of gametes.

Complete Answer
To find the correct answer to this question first you need to understand a few of the important concepts. Those are:
Haploid organisms: Those organisms having single chromosomes in their cells are called haploid organisms. Their chromosomes are represented as n ('n' is the number of chromosomes). Example: Ants
Diploid organisms: Those organisms having paired sets of chromosomes in their cells are termed as diploid organisms. Their chromosomes are represented as 2n ('n' is the number of chromosomes). Example: Humans
Mitosis: It is one of the natural methods of cell division taking place in living organisms. In this process, the parent cell divides to form two new independent daughter cells each having a pair of chromosomes.
Meiosis: It is another natural method of cell division taking place in living organisms. In this process, the parent cell divides two times producing four daughter cells, each having single chromosomes. It is followed by mitotic division of cells. Such a process is common only to sex chromosomes. Such as human sex cells.
The reason for this kind of division is that sex cells require to fuse with another cells of opposite gender to produce a normal diploid organism. However, in the case of haploid organisms, meiosis does not take place even for zygote formation due to which a number of chromosomes are preserved in upcoming generations as well.

Thus, we can say that the above given assertion is correct but the reason is incorrect. Therefore, option C is the correct option.

Note:
Mitosis is the simplest form of cell division. This kind of division is adopted in case of initiation of body growth in terms of size or replacement of old, wounded tissues. Whereas, meiosis is comparatively a complex process because it has multiple number of phases along with mitotic division.
