• Genotype and phenotype are interchangeable terms.

What is a dominant gene?

• A dominant gene is a gene that is always expressed, overriding the presence of a recessive gene.

• A dominant gene is a gene that is always recessive.

What is genetic variation?

• Genetic variation is the elimination of genes within a population.

• Genetic variation is the diversity in gene frequencies within a population.

• Genetic variation is the same genes present in all individuals within a population.

Explain the difference between mitosis and meiosis.

• Meiosis produces two identical daughter cells.

• Mitosis results in four non-identical daughter cells.

• Mitosis produces two identical daughter cells with the same number of chromosomes, while meiosis produces four non-identical daughter cells with half the number of chromosomes.

• Mitosis and meiosis both produce identical daughter cells.
