Text Solution

AI Generated Solution

To determine how many autosomes are found in a single mature human sperm, follow these steps: 1. **Understand the Total Chromosome Count in Humans**: Humans typically have 46 chromosomes, which can be organized into 23 pairs. This includes both autosomes and sex chromosomes. 2. **Identify the Types of Chromosomes**: Out of the 46 chromosomes, 22 pairs are autosomes, and 1 pair consists of sex chromosomes (XX for females and XY for males). 3. **Meiosis and Gamete Formation**: During the process of gamete formation (spermatogenesis in males), meiosis occurs. This process reduces the chromosome number by half. Therefore, each gamete (sperm or egg) will have half the total number of chromosomes. ...
