The correct Answer is:
To analyze the given assertion and reason, let's break down the concepts step by step: ### Step 1: Understand the Assertion The assertion states that "Multiplication occurs rapidly with equal rate in apomixis as well as in amphimixis." - **Apomixis** is a form of asexual reproduction where seeds are produced without fertilization. This process allows for rapid multiplication since it does not involve the complex processes of sexual reproduction. - **Amphimixis**, on the other hand, refers to sexual reproduction involving the fusion of gametes, which typically takes more time due to the processes of gamete formation, fertilization, and zygote development. **Conclusion for Step 1**: The assertion is incorrect because apomixis allows for rapid multiplication, while amphimixis does not occur at an equal rate. ### Step 2: Understand the Reason The reason states that "Both types show mitotic as well as meiotic division." - In **apomixis**, the process primarily involves mitotic division, as it is a form of asexual reproduction. This means that the offspring are genetically identical to the parent. - In **amphimixis**, meiosis occurs to produce gametes, which leads to genetic variation in the offspring. This involves meiotic division to reduce the chromosome number in gametes. **Conclusion for Step 2**: The reason is also incorrect because apomixis does not involve meiotic division, while amphimixis does. ### Final Conclusion Since both the assertion and the reason are incorrect, the correct answer is that both statements are false. ### Summary of the Solution 1. The assertion is incorrect because apomixis allows for rapid multiplication, while amphimixis does not occur at an equal rate. 2. The reason is incorrect because apomixis involves only mitotic division, whereas amphimixis involves meiotic division.

Fill up the balnks in the following paragraph by selecting the correct option. When migration of a section of population to another place and population occurs, I change in the original as well as in the new population new genes/ alleles are added to the ii, population and these are lost from the population. These would be a iv if this gene migration, happens multiple times. if the same change occurs by chance, it is called v. sometimes the change in allele frequency is so different in the new sample of population that they become a diffrent species. The original drifted population becomes founders and the effect is called vi
