The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Selfing**: Selfing, or self-pollination, occurs when a plant fertilizes itself. This process is common in many flowering plants. 2. **Effect of Repeated Selfing**: When self-pollination occurs repeatedly over generations, it leads to the production of offspring that are genetically similar to the parent plant. 3. **Homozygosity vs. Heterozygosity**: - **Homozygosity** refers to having two identical alleles for a particular gene (e.g., AA or aa). - **Heterozygosity** refers to having two different alleles for a gene (e.g., Aa). 4. **Outcome of Repeated Selfing**: With repeated selfing, the genetic makeup of the offspring tends to become more uniform, leading to an increase in homozygosity. This is because selfing reduces genetic variation and promotes the expression of the same alleles. 5. **Inbreeding Depression**: As homozygosity increases, there can be a loss of genetic diversity, which may lead to inbreeding depression. This condition can result in reduced fitness and vigor in the offspring. 6. **Conclusion**: Therefore, the correct answer to the question "Repeated selfing produces" is **homozygosity**. ---
