The correct Answer is:
To fill in the blanks in the given paragraph, we can follow these steps: 1. **Identify the concept of inbreeding**: Inbreeding refers to the mating of genetically similar organisms, which increases the chances of homozygosity, where individuals have identical alleles for a trait. 2. **Fill in the first blank**: The first blank requires a term that describes what inbreeding increases. The correct term is "homozygosity." Therefore, the first blank is filled as: - Inbreeding increases **homozygosity**. 3. **Fill in the second blank**: The second blank refers to what inbreeding is necessary for. Inbreeding is often used to develop a specific type of organism or breed. The correct term here is "pure line." Thus, the second blank is filled as: - This inbreeding is necessary if we want to evolve a **pure line** in any animal. 4. **Fill in the third blank**: The third blank pertains to the type of genes that inbreeding exposes. Inbreeding can reveal harmful traits that are typically recessive. Therefore, the third blank is filled as: - Inbreeding exposes harmful **recessive** genes that are eliminated by selection. Putting it all together, the completed paragraph is: "Inbreeding increases **homozygosity**. This inbreeding is necessary if we want to evolve a **pure line** in any animal. Inbreeding exposes harmful **recessive** genes that are eliminated by selection."
