Across
  1. 2. the dominant allele masks the effect of the recessive allele but not completely resulting in a phenotype that is a mixture of the two alleles.
  2. 3. a different version of a gene.
  3. 5. both alleles for a certain trait are the same.
  4. 7. inherited characteristics that vary from individual to individual.
  5. 9. both alleles are dominant; both alleles will try getting expressed with equal strength. As a result, the offspring will have both traits expressed.
  6. 11. a gene pair that has 2 different alleles for a trait.
  7. 14. the dominante allele will mask the effect of the recessive allele completely.
  8. 15. passing characteristics from one generation to the next.
  9. 17. a driagram that predicts outcomes of genetic crosses.
  10. 18. a cross used to study the inheritance of a single/one trait.
  11. 19. a cross used to study the inheritance of 2 different traits.
  12. 20. traits which are expressed when only one allele is present.
  13. 21. the study of heredity.
Down
  1. 1. more than two phenotypes exist for a specific trait.
  2. 4. says that the alleles if two or more different genes get sorted into gametes independently of one another.
  3. 6. the externally observable trait (physical).
  4. 8. traits which are only expressed when two alleles are present.
  5. 10. 2 alleles for a trait separate during meiosis. Each gamete receives only one allele.
  6. 12. the genetic makeup (genes)
  7. 13. a stretch of DNA within a chromosome that codes for a specific trait.
  8. 16. says that in a heterozygote, the dominant allele will be expressed exclusively.
