  1. 1. Another term for heterozygous (B b).
  2. 2. A dominant inheritance pattern in which the heterozygous genotype in which both alleles are partially expressed and often produces an intermediate phenotype.
  3. 4. A pair of alleles that are the same; either both dominant (B B) or both recessive (b b).
  4. 5. A square diagram that is used to predict an outcome of a particular genetic cross.
  5. 8. The pair of alleles responsible for a particular trait (represented by letters of the alphabet).
  6. 11. The passing of genetic information from parent to offspring.
  7. 12. A gene that can be masked by a dominant gene and is only expressed when two recessive alleles are present (b b).
  8. 13. A procedure used in which fetal cells are removed from the amniotic fluid and analyzed genetically.
  9. 14. A person that has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease.
  10. 15. A homozygous individuals that always produce offspring of the same phenotype when crossed together.

  1. 1. A pair of alleles that are different, where one is dominant & one is recessive (Ex. T t).
  2. 3. A trait that is expressed if at least one allele is present (T T OR T t).
  3. 6. The study of genes and heredity of living organisms.
  4. 7. An observable characteristic of an organism usually controlled by genes.
  5. 9. The physical appearance of an organism as a result of its genotype and the environment.
  6. 10. A diagram or family tree that shows the members of the family who are affected by a genetic trait.
  7. 13. One of two (sometimes more) alternative forms of a gene.
