- 2. A unit of heredity that is responsible for the transmission of traits from parents to offspring.
- 5. The father of modern genetics, who studied the inheritance of traits in pea plants and formulated the basic principles of inheritance, which became known as Mendelian genetics.
- 7. A change in the DNA sequence that can result in a new allele.
- 9. The allele that is expressed over its recessive counterpart in a heterozygous individual.
- 10. When an individual has two different alleles for a particular gene.
- 13. A cross between two individuals that differ in a single trait.
- 14. A variant form of a gene that can produce different traits in an organism.
- 15. The allele that is not expressed in a heterozygous individual unless it is present in a homozygous form.
- 16. A tool used to predict the possible genetic outcomes of a cross between two organisms.

- 1. Law of (blank)-A principle of genetics that states that the inheritance of one trait is not dependent on the inheritance of another.
- 3. The study of heredity and the passing of traits from parents to offspring.
- 4. Law of (blank)-A pattern of inheritance where one allele is dominant over another.
- 6. When an individual has two identical alleles for a particular gene.
- 8. Law of (blank)-A principle of genetics that states that each individual carries two alleles for each trait, which separate during the formation of gametes.
- 11. The physical expression of an organism's genetic traits.
- 12. The genetic makeup of an organism, including all of its inherited genes.
