To determine the number of chromosomes in each gamete of a mosquito, corn, a human, and a dog, we need to know the diploid (2n) chromosome numbers for each of these organisms and then divide by 2 to find the haploid (n) number.
1. **Mosquito**: The common house mosquito (*Culex pipiens*) has approximately 6 chromosomes in total (2n = 6), so each gamete (n) has 3 chromosomes.
2. **Corn** (maize): Corn has about 20 chromosomes in total (2n = 20), so each gamete (n) has 10 chromosomes.
3. **Human**: Humans have 46 chromosomes in total (2n = 46), so each gamete (n) has 23 chromosomes.
4. **Dog**: Dogs have a total of 78 chromosomes (2n = 78), so each gamete (n) has 39 chromosomes.
Now, let's list the number of chromosomes in each gamete:
- Mosquito: 3
- Corn: 10
- Human: 23
- Dog: 39
The series that lists these numbers is: **3, 10, 23, 39**.
So the correct answer is **3, 10, 23, 39**.
1. **Mosquito**: The common house mosquito (*Culex pipiens*) has approximately 6 chromosomes in total (2n = 6), so each gamete (n) has 3 chromosomes.
2. **Corn** (maize): Corn has about 20 chromosomes in total (2n = 20), so each gamete (n) has 10 chromosomes.
3. **Human**: Humans have 46 chromosomes in total (2n = 46), so each gamete (n) has 23 chromosomes.
4. **Dog**: Dogs have a total of 78 chromosomes (2n = 78), so each gamete (n) has 39 chromosomes.
Now, let's list the number of chromosomes in each gamete:
- Mosquito: 3
- Corn: 10
- Human: 23
- Dog: 39
The series that lists these numbers is: **3, 10, 23, 39**.
So the correct answer is **3, 10, 23, 39**.
