The correct Answer is:
To answer the question "Variations during mutations of meiotic recombinations are", we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Concepts**: - First, we need to understand what mutations and meiotic recombinations are. Mutations are sudden changes in the DNA sequence, while meiotic recombination is a process that occurs during meiosis where genetic material is exchanged between homologous chromosomes. 2. **Analyzing the Options**: - The options provided are: - A) Random and directionless - B) Random and directional - C) Random and small - D) Random, small, and directional 3. **Identifying Characteristics of Mutations**: - Mutations are generally considered to be random events that occur without a specific direction or purpose. This means that they can happen in various locations and do not follow a predictable pattern. 4. **Linking to Evolution**: - The theory of evolution, as proposed by Hugo de Vries, suggests that evolution is a spontaneous process. This implies that the variations arising from mutations are also spontaneous and random. 5. **Conclusion**: - Given that mutations are sudden and can occur in all conceivable directions, we can conclude that the variations during mutations of meiotic recombinations are "random and directionless". ### Final Answer: The correct option is **A) random and directionless**.
