Two traits that is starch Synthesis and shape of seed in pea is

Options

A. Two effects of same gene
B. Two different effects of group of genes
C. case of epistasis
D. Two different effects of group of genes

Answer

To solve the question regarding the traits of starch synthesis and seed shape in peas, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Traits**: The question mentions two traits: starch synthesis and the shape of seeds in peas. We need to determine how these traits are genetically related.

2. **Identifying the Genetic Basis**: In pea plants, the traits of starch synthesis and seed shape are controlled by specific genes. The gene responsible for starch synthesis can influence the physical characteristics of the seeds, such as their shape.

3. **Exploring Pleiotropy**: The phenomenon where one gene influences multiple traits is known as pleiotropy. In this case, the gene responsible for starch synthesis also affects the shape of the seeds. This means that variations in this single gene can lead to different outcomes in both traits.

4. **Analyzing the Alleles**: The gene for starch synthesis has two alleles: a dominant allele (let's say "B") that leads to high starch synthesis and a recessive allele (let's say "b") that results in lower starch synthesis. The dominant allele can also impact the shape of the seeds, leading to larger or different-shaped seeds compared to those produced by the recessive allele.

5. **Conclusion**: Since both traits (starch synthesis and seed shape) are influenced by the same gene, we conclude that these are two effects of the same gene. Therefore, the correct answer to the question is option A: two effects of the same gene.

### Final Answer:
The answer is **A: two effects of the same gene**.
