Answer 1

Here are the correct answers to your questions:

**Question 1: Which process increases genetic variation in a population?**
- **Mutation** (Mutations can introduce new genetic variations into a population's gene pool.)

**Question 2: Which of the following is a result of crossing-over during meiosis?**
- **Genetic recombination** (Crossing-over shuffles alleles between homologous chromosomes, leading to new combinations of genes.)

**Question 3: Genetic variation within a population is necessary for:**
- **Natural selection** (Genetic variation provides the raw material for evolution and enables populations to adapt to changing environments through natural selection.)
