The number of autosomes in human sperm are:

Options

A. 11
B. 22
C. 44
D. 45

Answer

To determine the number of autosomes in human sperm, we can follow these steps:

### Step 1: Understand the Chromosome Composition in Humans
Humans have a total of 46 chromosomes, which are organized into 23 pairs. This means that humans have 23 pairs of chromosomes, where each pair consists of one chromosome from the mother and one from the father.

**Hint:** Remember that humans have 46 chromosomes in total, which includes both autosomes and sex chromosomes.

### Step 2: Identify Autosomes and Sex Chromosomes
Out of the 46 chromosomes, 44 are autosomes, and 2 are sex chromosomes (XX for females and XY for males). Autosomes are the chromosomes that do not determine the sex of an individual.

**Hint:** Recall that autosomes are non-sex chromosomes, and in humans, there are 44 of them.

### Step 3: Understand the Process of Meiosis
Sperm cells are produced through a process called meiosis, which is a type of cell division that reduces the chromosome number by half. This means that the diploid number (2n = 46) is halved to the haploid number (n = 23) in gametes (sperm and eggs).

**Hint:** Meiosis results in a reduction of chromosome number, leading to haploid gametes.

### Step 4: Determine the Number of Autosomes in Sperm
Since sperm cells are haploid, they contain 23 chromosomes in total. Out of these 23 chromosomes, 22 are autosomes, and 1 is a sex chromosome (either X or Y).

**Hint:** In haploid cells, count the total number of chromosomes and remember to separate autosomes from sex chromosomes.

### Conclusion
Therefore, the number of autosomes in human sperm is **22**.

**Final Answer:** 22 (Option B)
