Across
  1. 2. bred from parents of the same breed or variety
  2. 4. Therapy/ an experimental technique that used genes to treat or prevent disease
  3. 5. the offspring of two plants or animals of different species or varieties
  4. 6. one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome
  5. 7. Engineering/ the process of using recombinant DNA technology to alter the genetic makeup of an organism
  6. 8. Inheritance/ occurs when one characteristic is controlled by two or more genes
  7. 10. the process of an animal or plant breeding with an individual of another species or variety
  8. 15. Allele/ refers to the relationship between between two versions of a gene; if the alleles of a gene are different, the allele that is expressed is the dominant gene
  9. 16. breed from closely related people or animals
  10. 18. a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring
  11. 19. the genetic constitution of an individual organism
  12. 20. Allele/ the effect of the other allele; not expressed
  13. 21. a distinguishing quality or characteristic
  14. 23. having two identical alleles alleles of a particular gene(s)
  15. 24. Alleles/ three or more possible alleles for one individual trait
Down
  1. 1. the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
  2. 2. the likelihood of something occurring
  3. 3. the passing on of physical or mental characteristics genetically from one generation to another
  4. 9. relationship between two versions of a gene
  5. 11. Breeding/ a process used by humans to develop new organisms with desirable characteristics
  6. 12. the action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote
  7. 13. Square/ a square diagram used to calculate and depict all the combinations and frequencies of the different genotypes and phenotypes among the offspring of a cross
  8. 14. having two different alleles of a particular gene(s)
  9. 17. Dominance/ when a dominant allele does not completely mask the effects of a recessive allele and the resulting physical appearance shows a blending of both alleles
  10. 19. the study of heredity and the variation of inherited characteristics
  11. 22. an organism or cell produced asexually from one ancestor or stock to which they are genetically identical
