During meiosis I in human, one of the daughter cells receives-

Options

A. Only maternal chromosomes
B. A mixture of maternal and paternal chromosomes
C. The same number of chromosomes as a diploid cell
D. Only parental cell

Answer

### Step-by-Step Solution:

1. **Understanding Meiosis I**: Meiosis I is the first division of meiosis, where a diploid cell divides to form two haploid cells. It involves the separation of homologous chromosomes.

2. **Homologous Chromosomes**: In humans, each diploid cell contains pairs of homologous chromosomes, one inherited from the mother and one from the father. For example, if we denote the father's chromosome as "A" and the mother's chromosome as "B", the homologous pair would be (A, B).

3. **Crossing Over**: During prophase I of meiosis, a process called crossing over occurs. This is where segments of DNA are exchanged between homologous chromosomes. This results in chromosomes that contain both maternal and paternal genetic material.

4. **Distribution of Chromosomes**: After crossing over, during metaphase I, the homologous chromosomes align at the cell's equatorial plane. When they are pulled apart during anaphase I, each daughter cell will receive a mix of maternal and paternal chromosomes.

5. **Resulting Daughter Cells**: Therefore, one of the daughter cells will receive a combination of maternal and paternal chromosomes due to the crossing over that occurred. This genetic recombination is essential for genetic diversity.

6. **Conclusion**: The daughter cells produced at the end of meiosis I will not be identical to the parent cell or to each other, as they will contain a mixture of genetic material from both parents.

### Final Answer:
During meiosis I in humans, one of the daughter cells receives a mixture of maternal and paternal chromosomes due to the process of crossing over.
