Which of the following is not a result of inbreeding?

• A. Higher prevalence of genetic disorders
• B. Increased homozygosity
• C. Reduced fitness in offspring
• D. Increased genetic diversity

Answer: (D)

Verified step by step guidance

1. Understand the concept of inbreeding: Inbreeding occurs when closely related individuals mate, leading to a higher chance of offspring inheriting the same alleles from both parents.
2. Recognize the effects of inbreeding: Inbreeding often results in increased homozygosity, where offspring are more likely to inherit identical alleles from both parents.
3. Identify the consequences of increased homozygosity: This can lead to a higher prevalence of genetic disorders, as harmful recessive alleles are more likely to be expressed.
4. Consider the impact on fitness: Inbreeding can reduce fitness in offspring, a phenomenon known as inbreeding depression, due to the expression of deleterious alleles.
5. Evaluate genetic diversity: Inbreeding does not increase genetic diversity; instead, it reduces it by limiting the variety of alleles in the gene pool.
