### Step-by-Step Solution: 1. **Understanding Sexual Reproduction**: Sexual reproduction involves two parents, typically a male and a female, contributing genetic material to produce offspring. Each parent has a specific number of chromosomes, which in humans is diploid (2n). 2. **Chromosome Number in Parents**: In humans, both the male and female parents have a diploid number of chromosomes, which means they each have 46 chromosomes (23 pairs). 3. **Formation of Gametes**: The male and female parents produce gametes (sperm and egg, respectively) through a process called meiosis. Meiosis is a type of cell division that reduces the chromosome number by half, resulting in haploid gametes. ...
