Which one of the following statement is correct

Options

A. Meiosis-I equivalent to mitosis division
B. The major objective of meiosis-I is segregation of homologous chromosome after recombination
C. The major objective of meiosis-II is Segregation of Homologous chromosome after Recombination
D. Division of chromosomes or centromere occurs during meiosis-I

Answer

To solve the question, "Which one of the following statements is correct?", we will analyze each statement provided:

1. **Meiosis I is equivalent to mitosis division.**
- Meiosis I and mitosis are two different types of cell division. In mitosis, one parent cell divides to form two identical daughter cells. Meiosis I, on the other hand, involves the separation of homologous chromosomes and results in two daughter cells that are not identical. Therefore, this statement is **incorrect**.

2. **The major objective of meiosis I is segregation of homologous chromosomes after recombination.**
- During meiosis I, homologous chromosomes are separated, and this process is preceded by recombination (crossing over) where genetic material is exchanged between homologous chromosomes. This statement accurately describes the process of meiosis I, making it **correct**.

3. **The major objective of meiosis II is segregation of homologous chromosomes after recombination.**
- Meiosis II primarily involves the separation of sister chromatids, not homologous chromosomes. Recombination occurs in meiosis I, not in meiosis II. Therefore, this statement is **incorrect**.

4. **Division of chromosomes or centromere occurs during meiosis I.**
- The division of centromeres occurs during anaphase II of meiosis, not during meiosis I. Therefore, this statement is also **incorrect**.

Based on the analysis, the correct answer is:
**The major objective of meiosis I is segregation of homologous chromosomes after recombination.**
