Answer
The term for the two sets of chromatids formed in the parent cell is **tetrad**.
Solution
1. In meiosis, homologous chromosomes pair up during prophase I to form structures called \( \textbf{tetrads} \).
2. Each tetrad consists of two homologous chromosomes, and each chromosome is made up of two sister chromatids. Thus, there are a total of four chromatids per tetrad.
3. Given the choices:
- **Haploid** refers to a cell with a single set of chromosomes.
- **Diplold** (presumably intended as "diploid") refers to a cell with two sets of chromosomes.
- **Tetrad** specifically describes the four chromatids (arranged in two homologous pairs) in the parent cell during meiosis.
- **Gamete** is a reproductive cell which is typically haploid.
4. Therefore, the correct term for the two sets of chromatids formed in the parent cell, arranged as described, is \( \textbf{tetrad} \).

The term for the two sets of chromatids formed in the parent cell is "tetrad." During meiosis, homologous chromosomes pair up and can exchange genetic material, but essentially, each chromatid within this paired structure can be thought of as forming a tetrad for that stage of the process. Interestingly, the tetrad stage is super important for increasing genetic diversity during reproduction! It allows for processes like crossing over, where genetic material is swapped between chromatids. This little twist in the tale of heredity is what makes every individual unique!
