  1. 4. the genetic information passing for traits from parents to their offspring, either through asexual reproduction or sexual reproduction
  2. 6. those that are expressed or seen when a heterozygous genotype is present
  3. 10. an organism that has two different alleles for the same trait
  4. 12. specialized cell involved in sexual reproduction
  5. 14. one in which the effect is not tangible, or is masked by the effects of the dominant gene
  6. 17. sequence of DNA that codes for a protein and determines a trait
  7. 18. dominance- situation in which one allele is not completely dominant over another
  8. 20. scientific study of heredity
Down
  1. 1. likelihood that a particular event will occur
  2. 2. offspring of crosses between parents with different traits
  3. 3. situation in which both alleles of a gene contribute to the phenotype of the organism
  4. 5. an organism that has two identical alleles for a particular trait
  5. 7. one of a number of different forms of a gene
  6. 8. themselves if allowed to self-pollinate
  7. 9. separation of alleles during gamete formation
  8. 11. square- diagram showing the gene combinations that might result from a genetic cross
  9. 13. breeding- describes organisms that produce offspring identical
  10. 15. alleles- a series of three or more alternative or allelic forms of a gene
  11. 16. physical characteristics of an organism
  12. 17. genetic makeup of an organism
