Select the correct arrangement of organisms in increasing order of the number of chromosomes present in their gametes.

Options

A. Cat Dog Potato Human
B. Dog Cat Potato Human
C. Dog Human Cat Potato
D. Cat Human Potato Dog

Answer

To solve the problem of arranging organisms in increasing order of the number of chromosomes present in their gametes, we need to follow these steps:

### Step 1: Identify the total number of chromosomes for each organism.
- **Cat**: 38 chromosomes
- **Dog**: 78 chromosomes
- **Potato**: 48 chromosomes
- **Human**: 46 chromosomes

### Step 2: Determine the haploid number of chromosomes (gametes) for each organism.
- The haploid number is calculated by dividing the total number of chromosomes by 2.
- **Cat**: 38 / 2 = 19 chromosomes in gametes
- **Dog**: 78 / 2 = 39 chromosomes in gametes
- **Potato**: 48 / 2 = 24 chromosomes in gametes
- **Human**: 46 / 2 = 23 chromosomes in gametes

### Step 3: List the haploid numbers obtained.
- Cat: 19
- Dog: 39
- Potato: 24
- Human: 23

### Step 4: Arrange the haploid numbers in increasing order.
- The order is:
1. Cat (19)
2. Human (23)
3. Potato (24)
4. Dog (39)

### Step 5: Write the final arrangement of organisms based on the increasing order of gamete chromosome numbers.
- The correct arrangement is: Cat, Human, Potato, Dog.

### Conclusion
The correct answer is the arrangement: **Cat, Human, Potato, Dog**.
