  1. 4. A trait that is expressed when at least one dominant allele is present.
  2. 6. The passing of traits from parents to offspring through genetic information.
  3. 11. The sequence of nucleotides (A, T, C, G) in DNA that determines the traits of an organism.
  4. 13. A trait that is expressed only when two recessive alleles are present.
  5. 15. Different forms of the same gene; can be dominant or recessive.

  1. 1. The organelle in a cell that contains the chromosomes and controls cellular activities.
  2. 2. The genetic makeup of an organism (e.g., AA, Aa, or aa).

  4. 5. A characteristic or feature of an organism, such as eye color or height, that is determined by genes.
  5. 7. The molecule that carries genetic information in all living organisms.
  6. 8. The process by which genetic information is passed from parents to offspring.
  7. 9. A change in the DNA sequence that can result in a different trait.
  8. 10. The basic unit of life, where DNA and chromosomes are located.
