  1. 1. The study of inherited variation.
  2. 5. Having two different alleles of a gene (for example, Aa).
  3. 6. A gene variant expressed when present in one copy.
  4. 10. The most common phenotype in a population for a particular gene.
  5. 11. Offspring resulting from true breeding.
  6. 13. An allele whose expression is masked by another allele.

  1. 1. The allele combinations in an individual that cause particular traits or conditions.
  2. 2. Offspring resulting from cross breeding.
  3. 3. The expression of a gene in traits.
  4. 4. Having two identical alleles of a gene (for example: AA or aa).
  5. 7. An allele that differs from the normal or most common allele in a population that alters a phenotype.
  6. 8. An alternate, or variant, form of a gene.
  7. 9. Transmission of inherited traits from generation to generation.
  8. 12. A sequence of DNA that codes for a specific protein.
