How many types of gametes are expected from the organism with genotype AABBCC :-

Options

A. one
B. Two
C. Four
D. Eight

Answer

To determine how many types of gametes can be produced from an organism with the genotype AABBCC, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Genotype**: The given genotype is AABBCC. This means:
- A is homozygous (AA)
- B is homozygous (BB)
- C is homozygous (CC)

2. **Understand Homozygosity**: In genetics, homozygous means that both alleles for a gene are the same. Since all three gene pairs (A, B, and C) are homozygous, there is no variation in alleles for these genes.

3. **Determine Gamete Formation**: Gametes are formed during meiosis, where alleles segregate. For each gene:
- For AA, the only allele that can be contributed to a gamete is A.
- For BB, the only allele that can be contributed to a gamete is B.
- For CC, the only allele that can be contributed to a gamete is C.

4. **Combine Alleles**: Since each gene can only contribute one type of allele due to homozygosity, the only possible combination of alleles in the gametes will be:
- A from AA
- B from BB
- C from CC

5. **Count the Types of Gametes**: Since there is only one combination of alleles that can be formed (ABC), there is only **one type of gamete** produced from the genotype AABBCC.

### Final Answer:
The number of types of gametes expected from the organism with genotype AABBCC is **1**.
