In mendel's experiment nature of seed coat , flower colour position of flower , podd colour sterm height etc ,are referred to as

Options

A. Alleles
B. Genotype
C. Phenotype
D. All of the above

Answer

To answer the question regarding Mendel's experiment and the traits he studied, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Traits**: Mendel studied various traits in pea plants, including the nature of seed coat, flower color, position of flower, pod color, and stem height. These traits are observable characteristics of the plants.

2. **Defining Phenotype**: The observable traits that Mendel studied are referred to as phenotypes. Phenotype is the physical expression of a trait, which can be influenced by the genotype (the genetic makeup) and the environment.

3. **Distinguishing Between Terms**:
- **Alleles**: These are different forms of a gene that can exist for a particular trait. For example, for flower color, there may be an allele for purple flowers and another for white flowers.
- **Genotype**: This refers to the genetic constitution of an organism, which includes the specific alleles it possesses. For example, a plant may have a genotype of TT (homozygous dominant), Tt (heterozygous), or tt (homozygous recessive) for a trait like stem height.
- **Phenotype**: As mentioned, this is the physical manifestation of the genotype. For example, a plant with the genotype TT or Tt will have a tall phenotype, while a plant with the genotype tt will have a dwarf phenotype.

4. **Conclusion**: Since the question asks about the traits studied by Mendel, which are based on physical characteristics, the correct term to refer to them is "phenotype."

### Final Answer:
The nature of seed coat, flower color, position of flower, pod color, and stem height in Mendel's experiment are referred to as **phenotypes**.
