Find out the incorrect statement.
(a) There are several pairs of constrasting characters of allotrophic traits
(b) Hybrids remain infertile
(c) Plants can be self fertilized
(d) Small herbaceous plants can be easily cultivated

Options

A. There are several pairs of constrasting characters of allotrophic traits
B. Hybrids remain infertile
C. Plants can be self fertilized
D. Small herbaceous plants can be easily cultivated.

Explanation

To find the incorrect statement among the given options, let's analyze each statement one by one.

**Step 1: Analyze Statement (a)**
- Statement (a): "There are several pairs of contrasting characters of allotrophic traits."
- Explanation: This statement refers to the presence of contrasting traits in organisms, which is a fundamental concept in genetics. Allotrophic traits can indeed have contrasting pairs, such as tall vs. short plants.
- Conclusion: This statement is correct.

**Step 2: Analyze Statement (b)**
- Statement (b): "Hybrids remain infertile."
- Explanation: This statement suggests that hybrids, which are the offspring resulting from the cross-breeding of different species or varieties, are infertile. However, this is not universally true. Many hybrids are fertile, such as mules (a hybrid of a horse and a donkey), while some hybrids may be infertile. Therefore, this statement is misleading.
- Conclusion: This statement is incorrect.

**Step 3: Analyze Statement (c)**
- Statement (c): "Plants can be self-fertilized."
- Explanation: Self-fertilization is a common reproductive strategy in many plants, especially those that are monoecious (having both male and female reproductive organs). This statement is true.
- Conclusion: This statement is correct.

**Step 4: Analyze Statement (d)**
- Statement (d): "Small herbaceous plants can be easily cultivated."
- Explanation: Small herbaceous plants are generally easier to cultivate due to their size and growth requirements. This statement is true.
- Conclusion: This statement is correct.

**Final Conclusion:**
The incorrect statement among the options is (b) "Hybrids remain infertile."
