  1. 3. mating of animals that are more alike in performance traits than the average of the herd or group
  2. 7. ratio of genetic variation to phenotypic variation
  3. 8. mating individuals that are closely related compared to the overall breed
  4. 10. offspring resulting of mating of two genetically similar animals (homozygous)
  5. 15. actual variation observed among animals for each specific trait
  6. 16. where an animal inherits the same alleles for a particular gene from both parents
  7. 17. presence of horns that are attached to the skull
  8. 19. mating of two genetically different animals of the same species
  9. 20. the study of heredity and how genes in all living things influence life
  10. 21. genetic makeup or allele combinations of animal
  11. 23. mating an animal of one breed with one from a second breed producing offspring that display a high degree of hybrid vigor
Down
  1. 1. observable or detectable characteristics of an individual organism
  2. 2. amount of variation that is controlled by genes
  3. 4. many breeds are used at the same time but are separated into groups
  4. 5. breeding animals with the same genetic line (family tree) but are not closely related as inbred animals
  5. 6. only expressed and visible when paired with another recessive allele
  6. 9. traits that are always expressed and the corresponding trait is seen, even if paired with a recessive allele
  7. 11. mating of animals that are less alike in performance traits than the aver­age of the herd
  8. 12. breed formed using two or more established breeds in exact percentages that vary based on the goals of the breed
  9. 13. mating of animals that are less closely related than most animals within the breed
  10. 14. absence of horns in an animal
  11. 18. genetic makeup of an individual (genotype) consisting of two different alleles of a gene for a particular trait
  12. 22. different forms (versions or copies) of the same gene
