In garden pea, starch is synthesised effectively in

Options

A. Heterozygous round seeded plants
B. Homozygous round seeded plants
C. Wrinkled seeded plants
D. Pure and hybrid round seeded plants

Answer

To answer the question "In garden pea, starch is synthesized effectively in which of the following seeds?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Genetics of Garden Pea**:
- The garden pea, scientifically known as Pisum sativum, has a diploid chromosome number of 2N = 14, meaning it has 7 pairs of chromosomes.

2. **Identify the Alleles for Seed Shape**:
- In garden peas, the allele for round seeds is dominant (represented as 'B'), while the allele for wrinkled seeds is recessive (represented as 'b').
- Therefore, the genotypes can be:
- Homozygous round seeds: BB (dominant)
- Heterozygous round seeds: Bb (dominant)
- Homozygous wrinkled seeds: bb (recessive)

3. **Determine Starch Synthesis**:
- Starch is synthesized effectively in plants with the homozygous dominant genotype (BB).
- In the case of heterozygous (Bb), starch is synthesized but not as effectively as in the homozygous dominant (BB).
- In homozygous recessive (bb), starch synthesis is minimal, resulting in wrinkled seeds.

4. **Evaluate the Options**:
- If the options include:
- Heterozygous round seeded plant (Bb)
- Homozygous round seeded plant (BB)
- Hybrid round seeded plant (Bb)
- Wrinkled seeded plant (bb)
- The only option that indicates effective starch synthesis is the homozygous round seeded plant (BB).

5. **Conclusion**:
- Therefore, the correct answer is that starch is synthesized effectively in the homozygous round seeded plant (BB).

### Final Answer:
Starch is synthesized effectively in the homozygous round seeded plant (BB).
