Question
**Question:** Genetic Recombination during meiosis creates ____________ within a particular species. **Options:** - a) mutation - b) variety - c) tension - d) cytokinesis **Explanation of Concepts:** 1. **Genetic Recombination:** - During meiosis, homologous chromosomes exchange genetic material in a process known as genetic recombination. This occurs during prophase I of meiosis and results in new combinations of alleles on the chromosomes. 2. **Meiosis:** - Meiosis is a type of cellular division that reduces the chromosome number by half, resulting in the production of four genetically unique gametes or sex cells (sperm in males and eggs in females). 3. **Options Analysis:** - Mutation: Refers to a change in the DNA sequence, which is a different process from recombination. - Variety: Refers to the genetic diversity or differences within a species, which is created by genetic recombination during meiosis. - Tension: Although tension does occur during chromosome separation, it is not an outcome of genetic recombination. - Cytokinesis: Refers to the division of the cytoplasm during cell division, which is a separate process from genetic recombination. The correct answer is **b) variety**, as genetic recombination during meiosis leads to genetic variation within a species. This genetic variety is essential for evolution and adaptation to changing environments.
