Consider the following statements and select the incorrect ones.
I. Honeybee has developed arrhenotoky in which the male develop from the fertilised egg and the female from unfertilised egg.
II. In the thelytoky, the haploid unfertilised egg parthenogenetically develop into females.
III. Heterogamy is the alteration between parthenogenesis and asexual reproduction.
IV. Parthenogenesis occurs naturally during reproducing in ants and aphids.
Choose the correct codes.

Options

A. I and IV
B. II and IV
C. II and III
D. I & III

Answer

To determine the incorrect statements from the given options, let's analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement I: Honeybee has developed arrhenotoky in which the male develops from the fertilised egg and the female from the unfertilised egg.**
- **Analysis:** This statement is incorrect. In arrhenotoky, males develop from unfertilised eggs (haploid) and females develop from fertilised eggs (diploid). Therefore, this statement misrepresents the process.

2. **Statement II: In thelytoky, the haploid unfertilised egg parthenogenetically develops into females.**
- **Analysis:** This statement is correct. Thelytoky is a type of parthenogenesis where unfertilised eggs develop into females. Thus, this statement accurately describes the process.

3. **Statement III: Heterogamy is the alteration between parthenogenesis and asexual reproduction.**
- **Analysis:** This statement is incorrect. Heterogamy refers to the alternation between sexual reproduction and parthenogenesis, not asexual reproduction. Therefore, this statement is misleading.

4. **Statement IV: Parthenogenesis occurs naturally during reproduction in ants and aphids.**
- **Analysis:** This statement is correct. Parthenogenesis is indeed observed in the reproductive cycles of ants and aphids, making this statement accurate.

### Conclusion:
The incorrect statements are:
- Statement I
- Statement III

Thus, the correct codes for the incorrect statements are **1 and 3**.

### Final Answer:
The correct answer is **Option 4: 1 and 3**.
