  1. 3. Mendelian law stating that two alleles for each trait separate during meiosis
  2. 4. Situation in which one allele is not completely dominant over another allele
  3. 7. Organisms with two of the same alleles for a trait
  4. 8. A person whose genotype includes a gene that is not expressed in the phenotype.
  5. 10. Traits controlled by genes located on X chromosomes.
  6. 12. The science of heredity
  7. 13. the law that states that genes separate independently of one another in meiosis
  8. 15. Another term for heterozygous organisms
  9. 17. The pair of alleles that an organism has (i.e. Xx, xx, or XX)
  10. 19. The occurrence of one or more extra sets of all chromosomes in an organism
  11. 21. Alleles that are masked in heterozygotes of a trait
  12. 22. Austrian monk whose experiments in breeding garden peas led to his eventual recognition as founder of the science of genetics (1822-1884)
  13. 24. A diagram that traces the inheritance of a particular trait through several generations
  14. 25. Alleles that control the trait that is shown

  1. 1. A condition in which both alleles for a gene are fully expressed
  2. 2. traits controlled by two or more genes
  3. 5. Organisms with two different alleles for a trait
  4. 6. A selective breeding method in whihc two individuals with different sets of alleles are crossed
  5. 9. The new combination of genes produced by crossing over and independent assortment
  6. 11. A selective breeding method in which two individuals with identical or similar sets of alleles are crossed
  7. 14. The process by which desired traits of certain plants and animals are selected and passed on to their future generations
  8. 16. The outward expression of a pair of alleles is known as that organism's (i.e brown hair, blonde hair, red hair)
  9. 18. the crossing of an individual of unknown genotype with a homozygous recessive individual to determine the unknown genotype
  10. 20. The passing of traits to the next generation
  11. 23. interaction between alleles in which one allele hides the effects of another allele
  12. 26. three or more forms of a gene that code for a single trait
