  1. 3. The "Father of Genetics," who worked with pea plants to understand how traits are passed.
  2. 5. A condition in which both alleles for a gene are fully expressed.
  3. 8. The physical appearance or visible traits of an organism.
  4. 11. are an organism’s genetic makeup, or allele combinations expressed as letters.
  5. 12. The different forms of a gene.
  6. 16. The process in which an egg cell and a sperm cell join to form a new organism.

  1. 1. An organism that is the offspring of many generations that have the same form of a trait.
  2. 2. An allele that is masked when a dominant allele is present.
  3. 4. An organism's genetic makeup with two identical recessive alleles.
  4. 6. A situation in which one allele is not completely dominant over another causing a mix of both traits.
  5. 7. The passing of traits from parents to offspring.
  6. 9. The likelihood that a particular event will occur.
