  1. 2. Trait that hides unless it gets two copies
  2. 3. Trait carried on the X chromosome — often affects males more
  3. 5. Symbol for a female on a pedigree
  4. 6. Blood phenotype type if genotype is ii
  5. 9. What the trait actually looks like — the visible result of your DNA
  6. 10. The actual alleles an organism has — genetic “behind the scenes”
  7. 13. Monk with a pea obsession who became the father of genetics
  8. 15. Alleles of different genes sort independently
  9. 16. Plant used to unlock the secrets of heredity — green and wrinkly never mattered so much
  10. 18. Family tree that tracks inherited traits
  11. 19. Trait controlled by many genes — like height or skin tone
  12. 22. Law sescribing alleles separating during gamete formation
  13. 23. 9:3:3:1Phenotypic ration seen in a __________ cross
  14. 24. One gene masks the effect of another
  15. 25. Two identical alleles — either double dominant or double recessive
Down
  1. 1. Neither allele is completely dominant — red + white = pink flowers
  2. 4. Handy tool for predicting offspring genotypes
  3. 5. Both alleles are fully expressed — like blood types A and B playing nice
  4. 7. Both genes and environment influence traits — it’s a team effort
  5. 8. Inheritance pattern where only one mutant allele is needed to show the trait
  6. 11. Different forms of a gene
  7. 12. A change in the DNA
  8. 14. Someone who has one copy of a recessive allele but shows no symptoms
  9. 17. Inheritance pattern where two copies are needed to express the trait
  10. 20. Two different alleles
  11. 21. Trait that shows up even with just one copy
