The correct Answer is:
To solve the question, "When two genetic loci produce identical phenotypes in cis as well as in trans position, they are considered to be," we will follow these steps: ### Step-by-Step Solution: 1. **Understand Genetic Loci**: - Genetic loci refer to specific locations on chromosomes where genes are found. Each locus can have different alleles (variants of a gene). 2. **Define Cis and Trans Positions**: - In genetics, "cis" refers to alleles that are located on the same chromosome and "trans" refers to alleles that are located on opposite chromosomes. 3. **Identical Phenotypes**: - The question states that the two genetic loci produce identical phenotypes in both cis and trans configurations. This means that regardless of whether the alleles are on the same chromosome or on different chromosomes, they result in the same observable traits. 4. **Consider the Concept of Pseudolinkage**: - Pseudolinkage occurs when two genes are closely linked on the same chromosome and behave as if they are alleles of the same gene. This can lead to identical phenotypes in both configurations. 5. **Conclusion**: - Based on the understanding that two genetic loci can produce identical phenotypes in both configurations (cis and trans), we conclude that these loci are referred to as "pseudoloci" or "pseudogenes." 6. **Final Answer**: - Therefore, the correct answer to the question is that the two genetic loci are considered to be **pseudoloci**.
