How many tetrads are visible in human meiocyte?

Options

A. 46
B. 23
C. 46 pairs
D. 23 pairs

Answer

To determine how many tetrads are visible in a human meiocyte, we can follow these steps:

### Step 1: Understand the Definition of Meiocyte
A meiocyte is a type of cell that undergoes meiosis to form gametes (sperm and egg cells).

**Hint:** Remember that meiocytes are involved in the formation of gametes through meiosis.

### Step 2: Understand Tetrads
Tetrads are formed during meiosis I when homologous chromosomes pair up. A tetrad consists of two homologous chromosomes, which together contain four chromatids.

**Hint:** Tetrads are formed from pairs of homologous chromosomes.

### Step 3: Determine the Number of Chromosomes in Humans
Humans have a total of 46 chromosomes in a somatic (body) cell, which are organized into 23 pairs of homologous chromosomes.

**Hint:** Recall that humans have 46 chromosomes, which can be grouped into pairs.

### Step 4: Calculate the Number of Tetrads
Since there are 23 pairs of homologous chromosomes in humans, during meiosis I, each pair will form one tetrad. Therefore, the number of tetrads visible in a human meiocyte is equal to the number of pairs of homologous chromosomes.

**Hint:** Each pair of homologous chromosomes forms one tetrad.

### Step 5: Conclusion
Thus, the number of tetrads visible in a human meiocyte is 23.

**Final Answer:** 23 tetrads.
