Outbreeding is the breeding of ________animals which may be between individuals of the same breed but having________

Answer

**Step-by-Step Solution:**

1. **Understanding Outbreeding**: Outbreeding refers to the practice of breeding animals that are not closely related. This is important for genetic diversity and improving the health and productivity of the offspring.

2. **Identifying the First Blank**: The first blank in the question asks for the type of animals involved in outbreeding. Since outbreeding involves breeding unrelated animals, we fill the first blank with "unrelated".

3. **Identifying the Second Blank**: The second part of the question specifies that these animals may be from the same breed but must have a certain relationship. In outbreeding, individuals from the same breed should not have common ancestors for a certain number of generations (typically four to six generations). Thus, we fill the second blank with "no common ancestors".

4. **Final Answer Construction**: Combining both parts, we conclude that "Outbreeding is the breeding of unrelated animals which may be between individuals of the same breed but having no common ancestors."

**Final Answer**: Outbreeding is the breeding of **unrelated** animals which may be between individuals of the same breed but having **no common ancestors**.
