Question

How many chromosomes are usually found in the human secondary oocyte?

• A. 22
• B. 44
• C. 46
• D. 23

Hint:

{Secondary oocyte = haploid = 23 chromosomes}.

Answer 1

The Correct Option is D

Step 1: Formation of secondary oocyte.
The secondary oocyte is formed after completion of meiosis I during oogenesis.
Step 2: Chromosome number.
After meiosis I, the cell becomes haploid and contains 23 chromosomes.
Step 3: Key point.
Although chromosomes are duplicated (chromatids), the chromosome number remains 23.
