Genetic traits of pea plants are note as follows :
(a) W -round, w-wrinkled
(b) Y - yellow , y - green
(c) T - Tall , t - dwarf
Which of the following is the genotype for a dwarf, winkled and yellow speeded plant ?

Options

A. Wwyyrr
B. RrYyTt
C. ttwwYy
D. ttWwTt

Answer

To determine the genotype for a dwarf, wrinkled, and yellow-seeded pea plant, we need to analyze the traits provided:

1. **Identify the traits and their genotypes:**
- **Seed Shape:**
- Round (W) is dominant.
- Wrinkled (w) is recessive.
- **Seed Color:**
- Yellow (Y) is dominant.
- Green (y) is recessive.
- **Plant Height:**
- Tall (T) is dominant.
- Dwarf (t) is recessive.

2. **Determine the genotype for each trait based on the given conditions:**
- **Dwarf Plant:** Since dwarfness is a recessive trait, the genotype must be homozygous recessive. Therefore, the genotype for height will be **tt**.
- **Wrinkled Seed:** Similarly, since wrinkled is also a recessive trait, the genotype must be homozygous recessive. Thus, the genotype for seed shape will be **ww**.
- **Yellow Seed:** Yellow is a dominant trait, which means the genotype can either be homozygous dominant (YY) or heterozygous (Yy). Therefore, the genotype for seed color can be either **YY** or **Yy**.

3. **Combine the genotypes:**
- For a plant that is dwarf (tt), wrinkled (ww), and yellow (YY or Yy), the possible genotypes can be:
- For homozygous yellow: **ttwwYY**
- For heterozygous yellow: **ttwwYy**

4. **Final genotype:**
- The genotypes for a dwarf, wrinkled, and yellow-seeded plant can be either **ttwwYY** or **ttwwYy**.

5. **Conclusion:**
- The answer will depend on the options provided in the question. If the options include either **ttwwYY** or **ttwwYy**, then either of those would be correct.
