Question:
The process in eukaryotes that results in the production of gametes is
The process in eukaryotes that results in the production of gametes is
Show Hint
Meiosis generates genetic diversity through crossing over (homologous recombination during prophase I) and independent assortment (during metaphase I).
Updated On: Jul 13, 2026
- Mitosis
- Meiosis
- Cytokinesis
- Karyokinesis
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Sexual reproduction in eukaryotes requires reducing the chromosome number by half to maintain a stable genome size across generations.
Step 2: Detailed Explanation:
- Meiosis is a specialized form of cell division that reduces the chromosome number in germ cells from diploid ($2n$) to haploid ($1n$).
- This division involves one round of DNA replication followed by two successive nuclear divisions (Meiosis I and Meiosis II).
- It produces four genetically distinct haploid gametes (sperm and egg cells in animals, or microspores and megaspores in plants).
- In contrast, mitosis maintains a constant chromosome number ($2n \rightarrow 2n$) and is used for somatic growth and vegetative propagation.
Step 3: Final Answer:
The cell division process that produces haploid gametes is meiosis.

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
In light of the above statements, choose the correct answer from the options given below. - The serum level of which of the following metabolites can effectively distinguish "Vitamin B12 deficiency" from "Folate deficiency" ?
