AI Generated Solution

The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding Inbreeding**: Inbreeding refers to the mating of closely related individuals, which leads to a higher chance of offspring inheriting the same alleles from both parents. 2. **Definition of Homozygosity**: Homozygosity is a genetic condition where an individual has two identical alleles for a particular gene. This means that both alleles are the same, leading to uniform traits. 3. **Impact of Inbreeding**: When inbreeding occurs, it tends to increase homozygosity in the population. This is because closely related individuals are more likely to carry the same alleles, which are then passed on to their offspring. 4. **Consequences of Increased Homozygosity**: While inbreeding can lead to the expression of desirable traits, it can also result in the expression of harmful recessive traits. This is because the chance of inheriting two copies of a recessive allele increases, which can lead to genetic disorders. 5. **Conclusion**: Based on the understanding of inbreeding and its effects, the correct answer to the question "Inbreeding increases ______" is "homozygosity". **Final Answer**: Inbreeding increases **homozygosity**. ---
